I expected rear-wheel drive sports cars, front-drive commuters and four-wheel drive trucks to look like three separate markets. On one measure they're indistinguishable.
| Drivetrain | Average mileage | Average age | Average price |
|---|---|---|---|
| Rear-wheel drive | 120,087 | 15.0 yrs | $16,320 |
| Front-wheel drive | 119,017 | 12.1 yrs | $10,584 |
| Four-wheel drive | 118,957 | 11.6 yrs | $20,197 |
1,130 miles separates the three
120,087, 119,017, 118,957. Under 1% between the highest and lowest, across 170,000 listings covering completely different kinds of vehicle at prices ranging from $10,584 to $20,197.
Meanwhile the age column spreads 3.4 years and the price column nearly doubles. The one thing that doesn't move is the odometer.
Mileage is the trigger, not age
The reading is fairly direct: owners decide to sell based on distance covered, not years elapsed.
It makes sense once you think about what's attached to mileage rather than to the calendar. Major services come due on distance. Tyres, brakes, belts, fluids — all mileage-based. The point at which a car needs a round of expensive maintenance is the point the owner reconsiders keeping it, and that arrives at a similar odometer reading regardless of what the car is.
Somewhere around 120,000 miles, enough of those items come due together that selling starts to look better than spending. That's the threshold, and it's remarkably consistent.
The age column tells the other half
Rear-wheel drive cars take 15.0 years to reach that mileage. Four-wheel drive takes 11.6. Same distance, three and a half years apart.
Rear-drive vehicles in the used market are disproportionately older sedans, sports cars and weekend vehicles — cars that get driven less per year. Four-wheel drive is trucks and SUVs doing real work: towing, commuting, covering distance. They arrive at the same odometer reading much faster.
So the age difference isn't about durability. It's about usage rate, the same effect we found in annual mileage by vehicle age.
What to do with it
Around 120,000 miles is when cars get sold, not when they die. A car at that reading is at a maintenance decision point, not the end of its life. Plenty run to 200,000 — we ranked the ones that actually do in cars that reach 200,000 miles.
Ask what was done before the sale. The seller reached the same fork you're now standing at. Either they did the work and sold anyway, or they didn't and that's why they sold. Records answer it; the car won't.
Judge age against mileage, not on its own. A 15-year-old rear-drive car with 120,000 miles is exactly average. An 11-year-old four-wheel drive with the same reading is also exactly average. Neither is remarkable, in either direction.
Confirm the reading is real. The whole pattern depends on odometers being honest, and a car sitting suspiciously below the threshold for its age is the profile rollbacks are designed to create. Recorded mileage history from a VIN check shows whether the numbers only ever moved forward.
Frequently asked questions
At what mileage do people sell their cars?
Around 119,000–120,000 miles, and it's remarkably consistent — rear-wheel drive listings average 120,087, front-wheel drive 119,017 and four-wheel drive 118,957, despite being different kinds of vehicle at different prices.
Why is the selling point based on mileage rather than age?
Because major maintenance is scheduled by distance. Tyres, brakes, belts, fluids and major services all come due on mileage, and around 120,000 enough of them cluster together that selling starts to look better than spending.
Why do four-wheel drive vehicles reach that mileage faster?
Usage rate. Four-wheel drive listings hit 118,957 miles at 11.6 years while rear-wheel drive takes 15.0 years to reach a similar figure, because trucks and SUVs do more work per year than the sedans and weekend cars that dominate rear-drive listings.
Is 120,000 miles too many for a used car?
It's the market average, not a limit. That reading marks a maintenance decision point rather than the end of a car's life — the question to ask is which of the due items the seller actually did before listing it.

I Priced Every Brand by the Miles It Has Left. RAM Costs Triple What Buick Does.
Everyone compares used cars on price and mileage separately. I combined them into one number — what you pay for every thousand miles the car still has in it — and the brand order came out completely different.
Tennessee Drivers Cover 62% More Miles Than Hawaiians
The same odometer reading means different things in different states. I divided mileage by age across tens of thousands of listings and found a 62% spread between the hardest-working cars in the country and the easiest life.
White Cars Went From 23% of the Road to 40% in Twelve Years
Park anywhere and count. Roughly two in five newish cars are white, and it wasn't always like that — in 2008 it was fewer than one in four. I sorted our listings by model year to watch the takeover happen.
