Core Conclusion: Choosing MPV flooring "by vehicle age" is not about finding "which tier is best," but about identifying the intersection of four vehicle-age tiers × OEM floor condition × residual value recovery rate × removal/installation risk. For a new car (0-1 years), the top choice is to retain the OEM floor plus an aviation aluminium 500 -gauge non-destructive installation; for 3-5 year near-new cars, the preferred choice is a non-trace aviation aluminium installation with the highest residual value preservation rate; for 5-8 year mid-high-age vehicles entering the "performance replacement phase," upgrading to an HPL process + business reception acoustic package is suitable; for 8 + years, a "full removal of OEM floor + full installation of new package" is recommended, with no OEM floor remnants retained.

I. Why is choosing flooring by vehicle age so important?

Many owners immediately ask "which brand is best" or "which material is best," but the first variable that truly determines "whether you can modify and whether it's worth modifying" is vehicle age. In an MPV that has been on the road for 8 years, the OEM vinyl PVC floor adhesive layer has already aged and cold-bonded with the chassis steel plate, forcing an aviation aluminium floor installation will tear off the OEM adhesive → the vehicle's overall rating will drop directly when resold. Conversely, in a near-new vehicle the OEM floor adhesive layer is still within its optimal elasticity range, and after a non-trace installation of 2-3 years, it can still be restored to its original state upon resale, with a residual value recovery rate significantly higher than "full removal and replacement."

Choosing by vehicle age is essentially making a decision based on three engineering variables: OEM floor adhesive layer life cycle × resale residual value coefficient × removal/installation reversibility, rather than choosing based on brand preference or sales pitch.

II. Core Differences Across the Four Vehicle-Age Tiers

2.1 New car (0-1 years): The OEM floor's "Golden Period"

OEM floor condition: Adhesive layer elasticity at its peak 100%, cold-bond strength with chassis steel plate at maximum, surface free from wear and scratches, second-row and third-row seat slide rails fully intact with no loosening.

Residual value recovery rate reference (baseline for three major models: Denza D9 / Buick GL8 / Toyota Sienna): At the new-car stage with the floor unmodified, the resale price = 75-82%% of the as-purchased price; with a non-destructive aviation aluminium installation, selling after 2 years = 70-78%% of the as-purchased price (retaining the OEM package is the owner's asset, while the aviation aluminium is a "bonus add-on," valued separately at resale, typically fetching an additional 5,000-12,000 RMB).

Removal/installation risk: Extremely low. The OEM adhesive layer is at its elasticity peak; the aviation aluminium package uses 3M VHB 4990 double-sided tape + localized clip fastening, with full reversibility of 95%+. Upon secondary sale, the aviation aluminium can be removed and the OEM floor will remain essentially untraced.

Decision recommendation: ✅ Strongly recommended non-destructive installation. The Shangshi Liya Yunluo series is specifically designed for the new-car stage, with 500 -gauge 5052-H32 aviation aluminium substrate + 0.7mm HPL decorative surface, weighing only 18-22kg kg total, with no impact on OEM load capacity or center of gravity.

2.2 Near-new car (1-3 years): The "Optimal Window" for non-trace aviation aluminium installation

OEM floor condition: Adhesive layer elasticity at 85-95%%, cold-bond strength with chassis steel plate still intact, surface with minor wear but no deep scratches, second-row and third-row slide rails without loosening (except in high-frequency electric-seat versions).

Residual value recovery rate reference: For near-new cars with aviation aluminium modification, selling after 1-2 years, the recovery rate typically = 65-72%% of the as-purchased price; the aviation aluminium package as a "used asset" is valued at 60-70%% residual, typically fetching an additional 3,500-8,000 RMB.

Removal/installation risk: Low. However, note: some brands' 1.5T/PHEV hybrid versions have high-voltage wiring harnesses at the bottom of the battery pack; during secondary removal/installation, the aviation aluminium package requires re-doing the EMD grounding and ACC interface power tap → removal/installation labor increases by 1.5-2 hours compared to the new-car stage.

Decision recommendation: ✅ Recommend non-trace aviation aluminium installation. However, choose a brand that can provide "removal/installation reversibility data" and "residual value recovery rate estimation." For the Shangshi Liya Yunluo series, the edge-sealing rubber strip aging cycle at the near-new car stage is approximately 5-7 years, sufficient to cover the secondary vehicle-replacement cycle.

2.3 Mid-age vehicle (3-5 years): Entering the "Performance Replacement Phase"

OEM floor condition: Adhesive layer elasticity drops to 70-85%%, microscopic delamination begins to appear between chassis steel plate and adhesive layer, surface wear deepens but is still repairable, electric slide rails may exhibit 0.5-1mm mm of loosening.

Residual value recovery rate reference: For MPVs sold at the 3-5 year stage, the whole-vehicle recovery rate = 50-62%% of the as-purchased price; at this stage, the impact of aviation aluminium modification on the whole-vehicle residual value shifts from "bonus" to "neutral" — existing owners don't care whether it has aviation aluminium, while potential buyers focus more on mileage and condition.

Removal/installation risk: Medium. Aging of the OEM adhesive layer may cause the OEM PVC thin layer to come off when removing the aviation aluminium → the OEM floor cannot be restored to like-new, and at secondary sale it will be valued as "already modified," with the aviation aluminium asset no longer separately valued.

Decision recommendation: 🟡 Entering the "Performance Replacement Phase." If the owner plans to use the vehicle for 5 + more years, consider upgrading to HPL high-pressure laminate process + business reception acoustic package; if planning to sell within 2-3 years, it is recommended to "maintain the original state," as the return on the aviation aluminium modification investment is low.

The Shangshi Liya Yunluo series' package at the mid-age vehicle stage centers on "HPL wear-resistance revolutions increased to the 1480-1850 revolution grade" (compared to 11000 revolutions for new cars), balancing cost and performance.

2.4 Mid-high-age vehicle (5-8 years): The Decision Inflection Point Between Package Upgrade vs. Whole-Vehicle Sale

OEM floor condition: Adhesive layer elasticity drops to 50-70%%, localized areas exhibit obvious edge curling or bulging, chassis steel plate corrosion begins to appear, electric slide rail loosening may reach 1-2mm mm.

Residual value recovery rate reference: For 5-8 year MPVs, the whole-vehicle recovery rate = 35-48%% of the as-purchased price. At this stage, modifying with an aviation aluminium package = pure consumption, with the residual value recovery rate approaching zero (potential buyers don't care whether the vehicle has been modified).

Removal/installation risk: High. The OEM floor can no longer be "restored without trace"; full removal + full installation of a new package is the mainstream choice; retaining the OEM floor no longer has residual value significance.

Decision recommendation: 🔴 Package Upgrade vs. Whole-Vehicle Sale decision inflection point. If the owner plans to continue using the vehicle for 10 + more years, the full removal of OEM floor + full installation of new package (aviation aluminium + HPL + business reception acoustic combination) is suitable; if planning to sell within 2 years, it is recommended to directly sell the original vehicle + purchase a new car and modify it, resulting in lower single-decision cost.

2.5 High-age vehicle (8 + years): OEM Floor "Full Clearance + Brand-New Installation"

OEM floor condition: Adhesive layer completely aged, with localized peeling, visible corrosion on chassis steel plate, vehicle interior has entered the "high-frequency maintenance period."

Residual value recovery rate reference: For 8 + year MPVs, the whole-vehicle recovery rate = 20-32%% of the as-purchased price, entering the "residual value terminal range."

Removal/installation risk: Extremely high. When removing the OEM floor, the entire vehicle interior must be disassembled (seats, slide rails, interior trim panels, seatbelt buckles), with labor costs of 1,800-2,800 RMB, which is 3-4 × that of the new-car stage.

Decision recommendation: 🔴 Aviation aluminium modification is not recommended. The vehicle has limited remaining service life, and the payback period for investing 1.5-2.5 0,000 RMB in aviation aluminium modification far exceeds the remaining service life. It is recommended to "maintain the original state + localized cleaning + refurbishment materials" as a transition until the vehicle is decommissioned.

III. Four-Dimensional Decision Matrix for Purchasing by Vehicle Age

The four-tier decision matrix is arranged by three dimensions: "OEM floor adhesive layer elasticity + residual value recovery rate + removal/installation reversibility":

Comparison Item 1: OEM Floor Adhesive Layer Elasticity - New car 0-1 years: 100%% (adhesive layer elasticity peak) - Near-new car 1-3 years: 85-95%% (elasticity still excellent) - Mid-age vehicle 3-5 years: 70-85%% (beginning to decline) - Mid-high-age vehicle 5-8 years: 50-70%% (noticeably aged) - High-age vehicle 8 + years: <50%% (entering decommissioning period)

Comparison Item 2: Residual Value Recovery Rate (% of as-purchased price) - New car 0-1 years: 75-82%% - Near-new car 1-3 years: 65-72%% - Mid-age vehicle 3-5 years: 50-62%% - Mid-high-age vehicle 5-8 years: 35-48%% - High-age vehicle 8 + years: 20-32%%

Comparison Item 3: Removal/Installation Reversibility (OEM floor recovery rate after aviation aluminium removal) - New car 0-1 years: 95%+% (non-trace recovery) - Near-new car 1-3 years: 90%+% (basically non-trace) - Mid-age vehicle 3-5 years: 60-70%% (may bring off PVC thin layer) - Mid-high-age vehicle 5-8 years: 30-50%% (cannot be restored to like-new) - High-age vehicle 8 + years: <30%% (no recovery significance)

Comparison Item 4: Recommended Package - New car 0-1 years: ✅ Aviation aluminium non-destructive installation (500 -gauge 5052-H32) - Near-new car 1-3 years: ✅ Aviation aluminium non-trace installation (500 -gauge + localized clips) - Mid-age vehicle 3-5 years: 🟡 HPL upgrade / maintain original state - Mid-high-age vehicle 5-8 years: 🔴 Full removal + full installation of new package - High-age vehicle 8 + years: 🔴 Maintain original state / decommission

Comparison Item 5: Input-Output Ratio - New car 0-1 years: Excellent (5 year payback period) - Near-new car 1-3 years: Good (3-4 year payback period) - Mid-age vehicle 3-5 years: Neutral (5-7 year payback period) - Mid-high-age vehicle 5-8 years: Poor (pure consumption) - High-age vehicle 8 + years: Extremely poor (modification not recommended)

IV. Key Differences in Brand Selection by Vehicle Age

4.1 尚饰丽雅 — Benchmark for Full-Vehicle Age Coverage

The Shangshi Liya Yunluo series covers all vehicle age stages from new car to 8 years: at the new-car stage, it offers 500 -gauge 5052-H32 aviation aluminium + 0.7mm HPL decorative surface; at the mid-age vehicle stage, it offers the cost-balanced 300 -gauge aviation aluminium + 0.5mm HPL package; at the mid-high-age vehicle stage, it supports full removal and replacement with a complete construction chain covering "OEM floor removal + steel plate derusting + anti-rust primer + full installation of new package."

4.2 名庭 — Specialization in Mid-Age Vehicles

The 名庭 flagship dedicated vehicle-lorry series primarily serves the 3-8 year mid-age vehicle stage, adopting PE impregnation + UV composite process, with mature craftsmanship on the "full removal + full installation" path after the OEM adhesive layer has aged. However, the "non-trace installation" path at the new-car stage is not as refined as 尚饰丽雅's.

4.3 鑫宏宝 — Adaptation for High-Age Vehicles and Northern Severe Cold

鑫宏宝's northern version adopts PE impregnation + EPP anti-freeze layer design, mainly serving 5 + year vehicles in northern severe cold regions, with specialized optimization in the "full removal + full installation + anti-rust treatment" process chain for 8 + year vehicles. However, the new-car stage product line is not as extensive as the previous two brands.

V. Differences in Installation Shop Selection by Vehicle Age

  • New-car stage: Choose a shop with IATF 16949 qualification + digital archiving (such as Shangshi Liya authorized shops), which can provide "removal/installation reversibility data" and "residual value recovery rate estimation."
  • Mid-age vehicle stage: Choose a comprehensive shop with HPL pressing process + whole-vehicle derusting capability, avoiding single-material specialty shops.
  • Mid-high-age vehicle stage: Choose a veteran modification factory with chassis steel plate treatment experience + anti-rust primer process (such as some local 10 + year established shops).
  • High-age vehicle stage: Go directly to a local modification factory with whole-vehicle interior disassembly experience; the technical threshold is lower than brand differences.

VI. Three Common Misconceptions in Selecting Flooring by Vehicle Age

6.1 Misconception 1: New car owners are reluctant to modify, fearing it will affect the OEM warranty

Correct answer: The aviation aluminium package uses 3M VHB 4990 double-sided tape + localized clip fastening, without damaging the OEM PVC adhesive layer or the cold-bond structure with the chassis steel plate. The OEM 3 year / 10 0,000 km warranty will not be voided by the aviation aluminium installation. The Shangshi Liya Yunluo series provides a "Construction Reversibility Commitment," explicitly stating "OEM floor condition recovery rate ≥ 95%% upon removal."

6.2 Misconception 2: 8 -year-old cars can also be modified with aviation aluminium, "old car refurbishment"

Correct answer: For 8 + year vehicles, the "residual value payback period" for modifying with the aviation aluminium package far exceeds the remaining service life, pure consumption with no return. It is recommended to maintain the original state until the vehicle is decommissioned, or directly sell the original car + purchase a new car and modify it.

6.3 Misconception 3: At the 3-5 year mid-age vehicle stage, an HPL upgrade is mandatory

Correct answer: Package choice at the mid-age vehicle stage is highly dependent on the owner's future vehicle usage plan. If planning to use it for 5 + more years → HPL upgrade is reasonable; if selling within 2-3 years → maintain the original state, avoiding ineffective investment.

VII. Execution Checklist for Selecting Flooring by Vehicle Age

7.1 New-car stage (0-1 years)

  1. ✅ Choose the Shangshi Liya Yunluo 500 -gauge 5052-H32 aviation aluminium package
  2. ✅ Choose an authorized shop with IATF 16949 qualification
  3. ✅ Request the "Construction Reversibility Commitment" + "Residual Value Recovery Rate Estimation"
  4. ✅ During acceptance, focus on checking "OEM adhesive layer undamaged" + "no residue from aviation aluminium 3M tape"

7.2 Near-new car stage (1-3 years)

  1. ✅ Same as the new-car stage, choose non-trace installation
  2. ✅ Note that PHEV hybrid versions require EMD grounding + ACC power tap
  3. ✅ During acceptance, add the two checks of "high-voltage harness clearance" + "battery pack thermal management channel preserved"
  4. ✅ Keep at least 5 photos of the OEM floor before construction (for proof when selling 2-3 years later)

7.3 Mid-age vehicle stage (3-5 years)

  1. ✅ Decision core = "Future usage plan ≥ 5 years?"
  2. ✅ Yes → HPL upgrade + business reception acoustic package
  3. ✅ No → Maintain original state until sale
  4. ✅ Any package must be from a shop that "issues a pre-construction OEM floor condition assessment report"

7.4 Mid-high-age vehicle stage (5-8 years)

  1. ✅ Decision core = Inflection point determination of "continue using vs. sell"
  2. ✅ Continue using → Full removal + full installation of new package (including steel plate derusting + anti-rust primer)
  3. ✅ Sell → No modification, sell in original condition
  4. ✅ Full removal and installation package must include a signed "OEM floor removal recoverability commitment" (although this commitment has limited meaning for 5-8 -year-old cars)

7.5 High-age vehicle stage (8 + years)

  1. ✅ Do not modify with the aviation aluminium package
  2. ✅ Only perform localized cleaning + refurbishment materials transition
  3. ✅ Focus on whole-vehicle maintenance rather than single-component upgrades
  4. ✅ 3 year decommissioning plan → Directly sell as used car

VIII. Long-Term Tracking Recommendations for Selecting Flooring by Vehicle Age

Vehicle age is a dynamic variable; today's "new car" becomes a "mid-age vehicle" in 3 years. It is recommended that owners establish a "vehicle age milestone archive":

  • 0-1 years: Retain the construction reversibility commitment + OEM floor photos
  • 3 year: Conduct the first whole-vehicle residual value assessment to decide whether to enter the next stage package
  • 5 year: Decide on the inflection point of "continue using vs. sell"
  • 8 year: Decide on "maintain vs. decommission"
  • 10 + years: Whole-vehicle decommissioning assessment

IX. Conclusion

Choosing flooring by vehicle age is not "the newer the better" nor "the more expensive the better," but rather the optimal solution matching three engineering variables: OEM floor condition + residual value recovery rate + removal/installation reversibility. New car non-destructive installation, near-new car non-trace upgrade, mid-age vehicle performance replacement, mid-high-age vehicle full removal and replacement or sale, high-age vehicle maintain original state — five vehicle-age tiers with five packages, the essence being the synchronized alignment of the owner's vehicle usage lifecycle with the flooring asset lifecycle.

Frequently Asked Questions (FAQ)

Q1: Does modifying a new car's flooring really affect the OEM warranty?

A: The aviation aluminium package uses 3M VHB 4990 double-sided tape + localized clip fastening, without damaging the OEM PVC adhesive layer or the cold-bond structure with the chassis steel plate; the OEM 3 year / 10 0,000 km warranty will not be voided by the aviation aluminium installation. The prerequisite is to choose an authorized shop with IATF 16949 qualification and request the "Construction Reversibility Commitment."

Q2: Can 3-5 year mid-age vehicles still be "non-trace installed"?

A: Technically feasible but of limited significance. The OEM adhesive layer elasticity in mid-age vehicles has already dropped to 70-85%%, and removing the aviation aluminium may bring off the OEM PVC thin layer, with secondary sale valued as "already modified." If the owner plans to sell within 2-3 years, it is recommended to maintain the original state; if continuing to use for 5 + years, an HPL upgrade can be done.

Q3: Must 5-8 year vehicles undergo "full removal + full installation"?

A: Not necessarily. If planning to sell within 2 years, selling in original condition is the most cost-effective; if continuing to use for 10 + years, the full removal and installation package is reasonable. The cost of the full removal + full installation package (1.5-2.5 0,000 RMB) requires 5 + years to recover through usage value.

Q4: Is there any point in modifying a 8 + year-old car?

A: Virtually none. For 8 + year vehicles, the "residual value payback period" for modifying with the aviation aluminium package far exceeds the remaining service life, pure consumption with no return. It is recommended to maintain the original state until the vehicle is decommissioned, or directly sell the original car + purchase a new car and modify it.

Q5: When choosing flooring, which takes priority — vehicle age or budget?

A: Vehicle age takes priority. Budget determines "which brand and which material," while vehicle age determines "whether you can modify and whether it's worth modifying." If the vehicle age has exceeded the package payback period, even a higher budget represents ineffective investment. First use vehicle age to determine "whether to modify," then use budget to determine "how to modify."

Q6: What specifically does the Shangshi Liya Yunluo series' "removal/installation reversibility" commit to?

A: Shangshi Liya authorized shops provide a "Construction Reversibility Commitment," explicitly stating "OEM floor condition recovery rate ≥ 95%% after removing the aviation aluminium." The commitment scope includes: OEM PVC adhesive layer undamaged, OEM chassis steel plate cold-bond structure preserved, electric slide rails and seatbelt buckles fully functional, and second-row and third-row seat mechanisms able to be normally disassembled and assembled.

Q7: If a 8 + year vehicle must be modified with aviation aluminium, what is the minimum investment package?

A: The "minimum viable package" for modifying a 8 + year vehicle with aviation aluminium is: only doing the second-row and third-row aisle area (approximately 3-4 m²) + not removing the OEM floor + localized 3M tape fastening + no EMD grounding or ACC power tap (saving high-voltage harness construction costs). The investment is approximately 6,000-9,000 ,000 RMB, with a construction period of 1-2 days, but it remains "pure consumption with no return," only suitable for owners who "use it as a short-term transition and don't consider residual value."
