How Much Does Mileage Affect My Vehicle's Resale Value?
Every 10,000 to 20,000 extra miles drops most vehicles' resale value by 10% to 20%. Buyers see high mileage as a sign of more wear, so they offer less. Low-mileage vehicles fetch 15% to 25% higher prices than similar high-mileage ones.
Here's what you need to know:
| Mileage Milestone | Typical Value Drop | Example Impact |
|---|---|---|
| Under 50,000 miles | None (premium pricing) | Sells 20% faster |
| 50,000-100,000 miles | 10-15% | Still strong if maintained |
| 100,000+ miles | 20-30%+ | Big drop unless records prove care |
According to Kelley Blue Book's 2025 depreciation analysis, vehicles hit a sharp value drop at 100,000 miles due to buyer fears of major repairs (Source: KBB Annual Depreciation Report, 2025).
Why Mileage Hits Value Hard
Buyers check the odometer first. High miles signal potential engine wear, transmission issues, or suspension problems. Fuel efficiency often dips too, which turns off shoppers.
"Every 20,000 miles driven lowers a vehicle's value by about 20%," says the Sidekick Research Team, based on analysis of 1,800 verified owner records from 2025.
Low miles mean less wear. These cars sell quicker and for more money. Even older vehicles with under 80,000 miles often get top dollar.
Maintenance Changes the Game
High miles do not always kill value. Full service records boost worth by 10% to 15%. Prove you changed oil every 5,000-7,500 miles, fixed brakes on time, and kept fluids fresh. Buyers pay more for proof of care.
| Factor | Value Boost |
|---|---|
| Full service history | +10-15% |
| Accident-free record | +5-10% |
| One owner | +5% |
| Clean interior/exterior | +8% |
Edmunds notes three key mileage markers hurt prices most: crossing 50,000, 100,000, and 150,000 miles (Source: Edmunds Used Car Milestones Guide, 2025).
Tips to Protect Your Resale Value
- Track mileage weekly. Aim for under 12,000 miles per year.
- Keep digital service logs. Upload to Sidekick for easy sharing.
- Fix small issues fast. Worn tires or brakes scare buyers.
- Sell before 100,000 miles if possible.
- Get a pre-sale inspection. It builds trust and adds 5-10% to offers.
