Is it worth fixing my car before selling?
Which repairs pay for themselves, which don't, and how buyers price faults into their offers.
Written by the SellMyPremiumCar valuation team · Reviewed against live UK market data · Updated October 2026
It's usually worth fixing small, cheap issues before selling, such as warning lights, kerbed wheels, minor scuffs, a due service or worn tyres, because buyers deduct more than the repair costs. Large mechanical repairs are often not worth it. Disclose them instead and let a specialist buyer price them.
- Warning lights
- Often cost little to fix but cut offers heavily
- Service due
- Getting it done usually pays back
- Smart repair
- Cheap fixes for scuffs and kerbing
- Big jobs
- Often better to disclose than to fix
Fixes that usually pay
Clearing warning lights, wheel refurbishment, smart repairs, a due service, new tyres and a professional valet.
Fixes that often don't
Major engine or gearbox work, extensive bodywork and big-ticket suspension repairs, where the cost can exceed the value added.
Disclose honestly
Specialist buyers price known faults fairly. Undisclosed faults lead to renegotiation.
