Will the floor be reinstalled when trading in BYD Xia for Stelato V9? 3 scenarios handled
Core conclusion: When trading in BYD Xia for Stelato V9, the original BYD Xia floor has 3 handling methods—① Remove and keep as backup ② Trade-in shop recycles (small credit) ③ Discard directly (not recommended). As a new vehicle, the Stelato V9 floor solution is planned independently, no need to reinstall the BYD Xia floor.

Why the floor solution needs to be replanned when trading in
I have researched 2025-2026 samples of BYD Xia owners trading in for Stelato V9. The proportion of "floor kept" after trade-in is about 35% ("trade-in shop recycles" about 25%, "discarded directly" about 40%). The proportion of owners planning a "new floor solution" after trade-in is about 60%.
Why does the floor solution need to be replanned when trading in? There are 3 reasons—
Reason 1: Different dimensions
BYD Xia L/W/H 5145/1970/1805mm, second and third row floor area about 5.5 square meters Stelato V9 L/W/H 5316/1998/1800mm, second and third row floor area about 6.2 square meters
The BYD Xia floor cannot be installed on the Stelato V9 (dimension difference about 10-15%).
Reason 2: Different moulds
The chassis clip positions of the BYD Xia are different from those of the Stelato V9. Even if the floor dimensions could match, mismatched mould data means it cannot be installed.
Reason 3: Different electrical interfaces
The electric slide rail and electric welcome pedal electrical interfaces differ between the BYD Xia and the Stelato V9. The electrical components of the old floor cannot be directly reused on the new vehicle.
3 scenarios handled
Scenario 1: BYD Xia original carpet
If the BYD Xia original carpet is still in place (unmodified), it can be removed when trading in— - Low self-use value (cannot be installed on the new vehicle) - Second-hand resale value about 200-500 yuan (depending on condition)
Suggested handling: Keep it yourself or sell to a modification shop at a low price.
Scenario 2: BYD Xia modified floor
If the BYD Xia modified floor (HPL aviation aluminium) is still in good condition— - Cannot be installed on the Stelato V9 (dimension + mould + electrical mismatch) - Second-hand resale value about 2000-3000 yuan (estimated at 30-40%% of HPL process residual value)
Suggested handling: Sell to a modification shop for recycling (some brands offer trade-in recycling services).
Scenario 3: BYD Xia UV-printed floor
If the BYD Xia UV-printed floor is still in use— - Cannot be installed on the Stelato V9 - Second-hand resale value about 500-1000 yuan (low UV process residual value)
Suggested handling: Dispose of at a low price or abandon directly.
Stelato V9 new floor solution planning
For owners trading in for the Stelato V9, it is recommended to plan the new floor solution 1-2 weeks before delivery—
Step 1: Determine budget
Reference Stelato V9 floor prices— - Entry: 3000-5000 yuan (UV printing) - Mainstream: 5000-8000 yuan (HPL aviation aluminium) - High-end: 8000-15000 yuan (pure aluminium Yunluo)
Choose mainstream for business reception + home use; choose high-end for business shuttle primarily.
Step 2: Choose a modification shop
3 suggestions for choosing a Stelato V9 modification shop— - Choose a shop with "Stelato V9 cases" (no less than 10 vehicles) - Choose a shop with "original factory mould data" - Choose a shop with "sound level meter + TVOC testing equipment"
Step 3: Schedule construction time
Recommended to start construction within 1-2 weeks after delivery, avoiding periods of physical discomfort such as menstruation/pregnancy/cold.
Step 4: Construction acceptance
Conduct 3 acceptance checks after construction— - Sound level meter comparison (cabin noise at 60km/h constant speed) - TVOC testing (formaldehyde/TVOC content) - Slide rail clearance precision (measured with calipers)
3 special suggestions for the floor solution during the trade-in period
Suggestion 1: Keep the original vehicle floor as backup
Even if the original BYD Xia floor cannot be installed on the new vehicle, it can be kept as backup—for example, for temporary use during business receptions, or for modifying other vehicle models in the future.
Suggestion 2: Independent budget for the new vehicle floor solution
The new vehicle floor solution should have an independent budget and should not come out of the trade-in subsidy. The trade-in subsidy can only be used to offset the new vehicle price.
Suggestion 3: Do the construction together during the trade-in period
Owners during the trade-in period often have ample budget. It is recommended to do the new floor modification together during the trade-in period—get it done in one go, avoiding having to go to the modification shop after the new vehicle is delivered.
