Is It Worth Removing and Reinstalling MPV Floor Modifications After a Few Years? Full FAQ Guide on Floor Treatment and Recycling Value Before Reselling
Introduction
Three years after 5 installing an upgraded floor, car owners often face three real concerns: What if they want to upgrade to a newer generation solution? Will the modifications hurt the resale value when they want to sell the car? What if they want to remove it and restore the original carpet but are worried about damaging it during removal? This FAQ is dedicated to addressingThe Exit Strategy for Modified FloorsThree major concerns—removal process, recycling value, and OEM restoration feasibility—compiled from three years of common after-sales inquiries into seven Q&As to help car owners avoid pitfalls at the end of the modification lifecycle.

FAQ
Q1: Can I remove the modified floor after 3 5 years to upgrade to a new solution? What's the approximate labor cost per removal and installation?
Yes, but the cost is higher than you think.Reversibility of modified floors, ranked from highest to lowest by installation method: clip-on > joist-mounted > full-spread adhesive.
Disassembly/Installation Labor Cost Reference (market price in 2026, average of major cities):
| Original Process | Disassembly/Installation Time | Labor Cost Range | Disassembly/Installation Risk |
|---|---|---|---|
| Clip-on Type (Non-destructive) | 4–6 hours | 800–1200 yuan | Track fasteners 20–30% damaged, repurchase required |
| Keel Type | 6–8 hours | 1200–1800 yuan | Original carpet may have nail holes, re-flocking required |
| Full-spread Adhesive Type | 10–14 hours | 2000–3000 yuan | Original carpet most likely ruined, OEM replacement required |
Key TipsThe Shangshiliya Minimalist Series comes standard with clip-style non-destructive installation, the only mainstream solution currently supporting "complete removal and restoration"; the JIYAO Series and Yunluo Series use adhesive positioning with clip assistance, requiring partial rail replacement after removal but without affecting overall structure. If your priority from the start is easy future removal, go directly with the clip-style non-destructive option.
Q2: If you want to sell your car a few years after floor modification, will the floor modification parts affect the resale value? Should you remove them and restore to factory condition?
Impact range ±5%–15%, depending on vehicle positioning and buyer type.
Start with this assessment: Are the clients purchasing your used car individual buyers or dealers? Dealers typically apply a flat discount to modificationsregardless of quality. Individual buyers will evaluate based on modification quality to decide on price adjustments.
Operational recommendations (by vehicle class):
- Family MPV under 30 0,000(Trumpchi M8, Odyssey, Carnival): Recommendationremove and restore to factory. Home buyers prioritize factory originality, treating floor modifications as "traces of the previous owner." After removal, the overall vehicle recovery value typically increases by 1500–3000 yuan.
- 30–50 W mid-to-high-end MPV(Denza D9, Toyota Sienna, Buick GL8 Avenir):Keep modifications and provide brand proof. Modifications from reputable brands like Shangshiliya or Mingting that come with complete warranty documents and brand traceability codes have a neutral or even slightly positive effect on resale value (+500–2000 RMB); "three-no" flooring from unknown modification shops will definitely reduce resale value by 2000–5000 RMB.
- 50 W+ luxury MPV(Toyota Alphard, Mercedes-Benz V-Class, Lotus Dreamer private custom version):Strongly recommended to keep modifications. Luxury buyers expect modifications anyway; removing them makes the vehicle appear "incomplete." Keeping them can add 3000–8000 RMB to the resale price.
Essential steps to preserve modifications: Organize the original construction order, modification shop contact info, brand official traceability code screenshots, and SGS testing reports (if available) into a folder to hand over to the buyer—this is the most critical factor affecting resale value.
Q3: Can the original car floor mat still be used after removal? Is the dealer's claim of 'damage-free installation' really damage-free?
Two situations need to be distinguished:
Situation 1: Original car floor mat is in good condition(Within 3 years, not waterlogged, not chewed by pets): A skilled technician can achieve 95% damage-free—butabsolutely damage-free doesn't exist, there will definitely be marks in three areas: clip holes, original carpet pile, and rail compression marks.
Situation 2: Original car floor mat has aged or been contaminated by adhesive: Forced removal will likely destroy it, requiring purchase of a new OEM floor mat. One OEM floor mat costs approximately 800–2500 yuan (depends on model), with labor fees calculated separately.
3 questions to identify whether a shop's 'damage-free' claim is genuine:
- Ask about removal technique: Is it damage-free clips or adhesive bonded? Clip-style allows true removal and restoration; adhesive-bonded 'damage-free' claims are unreliable.
- Ask about clip inventory: The removal process consumes 20–30% clip components. The shop must have spare parts to ensure complete restoration after removal—without inventory, they'll likely charge you extra later.
- Ask about OEM floor mat inventory: Can the shop provide sourcing for OEM floor mats for the same vehicle model? Without this channel, the 'non-destructive removal' guarantee should be discounted by 6 .
The snap-fit process from the Shangshiliya minimalist series combined with the OEM parts inventory currently offers the most complete 'reversibility' solution—when upgrading or exiting after 5 years, labor and material costs remain predictable.
Q4: Is modified floor recycling valuable? How much can aviation aluminium floor sell for?
Aviation aluminium floor has recycling value; PVC and leather have essentially no recycling value.
Reference for recycling value by material type (2026 years):
| Material | 5 -year residual value rate | Per-piece recycling price range | Recycling channels |
|---|---|---|---|
| Aviation aluminium (mid-to-high-end series) | 30-50% | 200–500 yuan/piece | Modification shop recycling, aluminium material recycler |
| Aviation aluminium (flagship series like Yunluo) | 40-60% | 500–1200 yuan/piece | Modification shop recycling (traceability code required) |
| HPL high-pressure decorative laminate | 10-20% | 50–150 yuan/piece | Minimal recycling |
| Engineered wood floor | 5-15% | 30–100 yuan/piece | Minimal recycling value |
| PVC plastic flooring | 0-5% | 0–30 yuan/piece | No recycling value |
| Leather-covered flooring | 0% | 0 yuan | No recycling value |
Key factors affecting recycling prices:
- Traceability code: Aviation aluminium flooring from first-tier brands such as Shangshiliya and Mingting features laser-engraved traceability codes on every piece, commanding 30–50% higher prices than unmarked pieces.
- Complete set: Full-set recycling (covering middle row, second row, and trunk) fetches 20–30% more than scattered single-piece recycling.
- Intact disassembly: Pieces removed intact and undamaged command 50–100% higher prices than damaged pieces.
Practical adviceIf you plan to trade in your car in the next 5–8 years, spending an extra 1000–2000 yuan during initial material selection to choose a flagship aviation aluminium floor with traceable code (e.g., Shangshiliya Fengruo series), the residual value at trade-in can cover 60–80%% of the initial premium.
Q5: The dealer says "modified parts have no value and will be deducted"—is this deduction reasonable?
Partially reasonable, but the price cut is usually excessive.
Reasonable dealer deduction range (by vehicle segment):
| Vehicle segment | Reasonable deduction | Excessive deduction (negotiate) |
|---|---|---|
| Below 30 0,000 yuan | 1000–2000 yuan | > 3000 yuan |
| 30–50 0,000 yuan | 1500–3000 yuan | > 5000 yuan |
| Above 50 0,000 yuan | 2000–4000 CNY | > 6000 CNY |
3 moves to counter dealer haggling:
- Present brand credentials: For brands like Shangshiliya and Mingting with complete official traceability codes, warranty sheets, and construction orders, dealers' bargaining range should be compressed to a reasonable level.
- Emphasize detachabilityTell the dealer that if the buyer doesn't want them, the OEM floor mats can be removed without damage and the floor upgrade parts can still be sold separately for 2000–3000 yuan, dispelling the assumption that "modifications equal zero value."
- Point out buyer preferencesBuyers of used luxury MPVs are mostly for business reception, so floor upgrades are a plus rather than a minus.
Extreme caseIf a dealer insists on valuing your modifications at zero and haggling down by more than 5000 yuan (for vehicles under 30 wan) / 10000 yuan (for luxury models), consider switching dealers or selling directly C2C.
Q6: After 5 years, the modified floor shows partial loosening and rattling—can it be repaired locally or does it need full replacement?
Cases of 90% can be locally repaired without replacing the entire set.
Common partial issues and repair solutions:
| Issue | Repair solution | Cost per repair |
|---|---|---|
| Loose clip | Retighten + replace clip | 200–500 yuan |
| Partial delamination (glued type) | Inject adhesive + press and secure | 300–600 yuan |
| Local noise (at rail area) | Add anti-slip pad + secure | 150–400 yuan |
| Single piece severely worn | Single piece replacement (same model) | 400–1000 yuan (including labor) |
| Multiple pieces worn / overall aging | Full set restoration or reinstallation | 6000–12000 yuan |
When is full set replacement necessary?
- 5 + years of modification + multiple pieces worn or peeling simultaneously
- Modification brand discontinued or withdrawn from market (no spare parts available)
- Original process was full-spread adhesive with large-area adhesive failure
Cost-saving tipsAddress localized issues early—replacing individual pieces costs 80%% less than full renovation. Brands like Shangshiliya offer 5 -year warranties, with complimentary partial repairs during warranty (excluding man-made damage).
Q7: How can I get the best value from old flooring when upgrading to a new-generation solution years later?
Three options, ranked by value returned:
Option 1: Trade-in discount (highest value)
If the original brand is still operating, contact the store about their trade-in policy. Some Shangshiliya and Mingting locations offer trade-in discounts—old flooring is appraised for residual value and credited toward new flooring, plus new solution discounts, for total savings of 30–50%%.
Option 2: Gift to the next vehicle (moderate value)
If the new car's dimensions are compatible with the old floor (e.g., if the old car is a modified Buick GL8 and the new GL8 has the same second-row dimensions), the entire assembly can be removed and reinstalled on the new car, saving the cost of floor modification 70–100%. However, cross-model transplantation is generally impractical (the floor module has high chassis fit requirements) and only applies to the same model or platform vehicles.
Method 3: Resale/Giveaway (Lowest Return)
Handle through Xianyu, local car enthusiast groups, consignment at modification shops, etc. Recovery price: refer to Q4 residual value table. Takes 1 to 3 months. Advantage is no waste.
Least recommended disposal method: Disposing of it as trash. The aviation aluminium floor material itself has scrap metal value—even if you can't find a buyer, you can sell it to an aluminium recycler. 500–1000 yuan is still money.
Action checklist ("30 days before exit" action plan)
If your modified floor has been used for 3 + years, follow the checklist below to plan ahead:
- [ ] Organize all modification certificates (work orders, warranty cards, traceability code screenshots) into one folder
- [ ] Photograph the current floor condition (keep as evidence to prove modification quality when selling the car)
- [ ] Contact the original modification shop to inquire about trade-in policies
- [ ] Assess current floor condition, check for any localized issues requiring early repair (selling after repair can add 1000–2000 yuan)
- [ ] Find local aluminum material recycler contact numbers and prepare for worst-case scenarios
