"Twelve thousand a year" is the figure every valuation assumes. It's a national average, and national averages hide the interesting part. I took every listing from 2010 to 2022, divided the odometer by the car's age and grouped by state.
| State | Listings | Miles per year |
|---|---|---|
| Tennessee | 2,795 | |
| Missouri | 4,367 | |
| Georgia | 3,291 | |
| Michigan | 3,300 | |
| Washington | — | |
| Nevada | — | |
| Hawaii | — |
A Tennessee car covers 14,555 miles a year. A Hawaiian one does 8,989. Same model, same age, and one has done 62% more work than the other.
Geography does most of it
Hawaii is the obvious case: you cannot drive far on an island. The longest continuous drive on Oahu is under fifty miles, so cars accumulate mileage in short, repeated trips and the odometer stays low for years.
The high end is the opposite. Tennessee, Missouri and Georgia are states where the commute is long, the interstates are busy and public transport is thin. Michigan is a slightly different story — long distances plus a working-vehicle culture.
Nevada is the surprise at 11,299. You'd expect desert distances, but the population is concentrated in Las Vegas and Reno, and city driving racks up hours rather than miles.
Why this matters when you buy
Because the odometer is the single biggest lever on price, and it means different things depending on where the car has lived.
A ten-year-old Hawaiian car with 90,000 miles has led an average life for its state. The same car from Tennessee would have 145,000. If you're judging "high mileage" against the national figure, you'll overpay for one and dismiss the other.
And the miles themselves differ in kind. High-mileage states rack up motorway miles, which are gentle — steady load, few cold starts, minimal brake wear. Low-mileage island and city driving is mostly short trips, which is the harshest thing you can do to an engine: it never reaches temperature, oil doesn't circulate properly, condensation builds in the exhaust.
So a 145,000-mile Tennessee car can genuinely be in better mechanical condition than a 90,000-mile Honolulu one. That's not a hypothetical — it's the practical consequence of the table above.
The other thing state tells you
Salt. A Michigan car has spent a decade on treated winter roads, and rust is the failure that ends cars in the rust belt regardless of how the engine is doing. That's why southern and western trucks command a premium that doesn't always show in the asking price.
So the state on the listing gives you two independent facts: how hard the car has probably worked, and what the underside probably looks like. Neither appears on the odometer.
How to use it
Divide the odometer by the car's age before you react to the number, then compare with the state it's from rather than the national average. Between 10,000 and 17,000 a year is ordinary almost anywhere; well outside that range in either direction deserves a question.
Then confirm the reading is real. Every title transfer records mileage, and a free VIN check shows whether the sequence makes sense — a number that goes backwards, or a long gap with no record, is the thing you're looking for. We covered the wider curve in how many miles cars actually do per year.
Frequently asked questions
Which state drives the most miles per year?
Tennessee, at 14,555 miles a year in our listings, followed by Missouri (13,871), Georgia (13,832) and Michigan (13,550). Hawaii is lowest at 8,989.
Why do Hawaiian cars have such low mileage?
Geography. The longest continuous drive on Oahu is under fifty miles, so cars accumulate mileage in short repeated trips rather than long journeys.
Is a high-mileage car from a rural state worse?
Often the opposite. High-mileage states accumulate motorway miles, which are gentle — steady load, few cold starts. Low-mileage city and island driving is mostly short trips, which is harder on an engine that never reaches operating temperature.
What else does the state tell me about a used car?
Corrosion exposure. Cars from salted-road states carry rust risk regardless of mechanical condition, which is why southern and western vehicles command a premium at the same mileage.

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.
New Cars Do 16,800 Miles a Year. Ten-Year-Old Ones Do 12,000.
Everyone quotes 12,000 miles a year as the standard. The listings say that number is only true for a decade-old car — new ones do far more, old ones far less, and knowing which end you are on changes what counts as high mileage.
The Worst Year for Depreciation Isn't the First One
Everyone knows a new car loses money driving off the lot. The data says the first year is the gentlest, and the real cliff comes later.
