Mileage is one of the first things buyers look at — but it's often misunderstood. A car with 120,000 miles isn't automatically a bad buy, and a car with 50,000 miles isn't automatically a good one. Here's how to actually think about it.
The average American drives about 15,000 miles per year. So for a quick check, multiply the car's age by 15,000 and compare it to the odometer. A 5-year-old car at 75,000 miles is "average." At 45,000, it's low. At 110,000, it's high.
High mileage isn't a dealbreaker — it's a negotiating point. A well-maintained Honda with 130k miles can easily outlast a neglected one at 60k.
Modern cars are built better than they were 20 years ago. Most well-maintained vehicles can reach 200,000+ miles with no major issues. Here's a rough guide:
A car that's had regular oil changes, fluid flushes, and scheduled maintenance at 120,000 miles is a far better buy than one that's been neglected at 70,000. Always ask for maintenance records. If the seller can't produce them, that's a red flag — not the mileage number.
Not all miles are equal. Highway miles are easier on an engine than city miles. A car driven mostly on the highway at steady speeds puts less wear on the engine, brakes, and transmission than one that spent its life in stop-and-go traffic. A car used for long commutes at 80k miles may actually be in better shape than a city car at 60k.
Some brands are well-known for longevity at high mileage. Toyota (Camry, Corolla, Tacoma, 4Runner), Honda (Civic, Accord, CR-V), and Lexus consistently top reliability rankings at 100k+ miles. On the other end, some European luxury brands become expensive to maintain beyond 80,000 miles due to parts and labor costs.
Estimate what a used car is worth based on mileage, age, and condition.

A 10-year-old Toyota at 140,000 miles with full service records is a better buy than a 6-year-old German sedan at 65,000 miles with no paperwork. Focus on the make, maintenance history, and a pre-purchase inspection — the number on the odometer is just a starting point.
A car that's old but low-mileage isn't necessarily better than a high-mileage car. Rubber seals, belts, and hoses degrade with age regardless of miles driven. A 12-year-old car with 50,000 miles may have more age-related issues than a 7-year-old car with 90,000 miles. When evaluating a used car, consider both age and mileage together rather than either in isolation.
Rubber components, coolant hoses, belts, and brake fluid all have time-based service intervals, not just mileage-based ones. If a car is 10+ years old and has no record of these services being performed, budget for them even if the mileage looks great.
As a rough rule, every 10,000 miles above average (typically 12,000–15,000 miles per year) reduces a used car's value by $1,000–$2,000 depending on the make and model. A 5-year-old car with 90,000 miles (18,000/year) carries a meaningful discount versus the same model with 60,000 miles. This is reflected in private party prices and dealer listings alike.
Use this to your advantage when negotiating. If a car has significantly above-average mileage for its age, that's a legitimate basis for a lower offer — especially if repairs are likely coming sooner.
Not all high-mileage used cars are equal. Some brands consistently demonstrate longer service lives than others. Toyota and Honda are widely regarded as the most reliable at high mileage, with many Camrys, Corollas, Civics, and Accords reaching 200,000+ miles with basic maintenance. Lexus, Mazda, and Subaru also have strong reputations for longevity.
Brands with more complex electronics, air suspensions, or turbocharged engines that require premium fuel tend to have higher repair costs at high mileage. This doesn't make them bad cars, but it does mean the risk profile is different when you're buying at 100,000+ miles.
