Why mileage changes the math
Two things happen as the odometer climbs, and they pull in opposite directions. The repairs get more likely and more expensive: the failures that end up towed are late-life failures, and the dearest of them — an engine past $9,000, a transmission past $6,500 — are the ones a high-mileage car is closer to. Those are the national averages we publish at what car repairs actually cost, not quotes.
At the same time, what you can buy narrows. Every plan has eligibility rules for age and mileage, the broadest tiers are built for younger vehicles, and the price of the same coverage rises with the odometer. We are deliberately not printing cutoffs here: they are plan- and state-specific, and a number on a marketing page is not the number that binds anyone. What we can say plainly is that at this mileage every quote is mileage-specific — and that waiting is not free, because a quote at your current mileage and one ten thousand miles from now are different quotes, and the second is rarely the better one.
What to check before you buy on an older car
On a newer car the contract's fine print is background. On a high-mileage car it is the product. Four things to do before any signature, on our contract or anyone else's.
