Buyer's Guide
What to know before you buy, plus what we have on the lot right now.
Good mileage on a used car isn't a single number. A well-maintained vehicle with 100,000 miles can be a better buy than a neglected one with half that. Look at maintenance history and driving conditions alongside the odometer reading before you decide.
Modern vehicles are built to last longer than they used to, so a used car with over 100,000 miles can still have plenty of life left if it's been well maintained. Mileage is a useful starting point, but two cars with the exact same odometer reading can be in very different condition depending on how they were driven and cared for. That's why it's worth looking past the number on the dashboard before you decide.
A full maintenance record tells you far more than mileage alone. Ask for service records showing regular oil changes, fluid replacements, and any major repairs. A car with consistent, documented maintenance and higher mileage is often a safer bet than a car with low mileage and gaps in its service history, since skipped maintenance can cause problems that don't show up until well after you've bought the car. Our certified technicians can also inspect a specific vehicle and point out anything the paperwork alone wouldn't reveal.
Not all miles wear a car equally. A vehicle that spent most of its life on flat highway miles in a dry climate typically holds up better than one that logged the same mileage in stop and go traffic or a harsh, wet climate. Frequent stop and go driving puts extra strain on the transmission and brakes, while cold, wet, or salty conditions speed up rust and wear on the undercarriage. Ask where a vehicle spent most of its life and whether it was garaged or parked outside, since that history matters as much as the number on the odometer.
When comparing a newer model year with higher mileage against an older one with lower mileage, both sides of that trade matter. A low mileage vehicle that sat unused for long stretches can develop its own issues, since seals and drivetrain components benefit from regular use. A car with a spotless maintenance record and moderate mileage is often the stronger choice over one with fewer miles but a spotty service history. Late model year vehicles with low mileage tend to carry a premium price, so it's worth weighing whether a slightly older model, or a new vehicle lease special, gets you more value for the same budget.
| Scenario | What It Usually Means |
|---|---|
| High mileage, full service history | Often a solid, dependable buy |
| Low mileage, gaps in service history | Worth extra inspection before buying |
| High mileage, highway driven | Typically less wear than the same mileage in stop and go traffic |
| Low mileage, sat unused for long periods | Check seals, fluids, and tires for age related wear |

Beyond the paperwork, a few physical clues can tell you how a vehicle has actually been treated. Even tire wear across all four tires suggests regular alignment and rotation. Clean pedal rubber and interior surfaces relative to the mileage can point to lighter use than the odometer suggests. A clean engine bay without leaks, and fluids that look fresh rather than dark or gritty, are both good signs. None of these replace a proper inspection, but they're worth noticing on a test drive before you get an expert opinion.
Mileage plays into what a vehicle is worth when you eventually sell or trade it in, even when the car is running well. Buyers and appraisers both use mileage as a quick reference point, so a higher mileage vehicle typically carries a lower resale value than a lower mileage version of the same model and year, regardless of how well it's been maintained. Factor that into your decision if you plan to trade the vehicle in again within a few years rather than keep it long term.
A short list of questions can tell you a lot before you even open the hood: how many owners has the vehicle had, was it used for commuting, towing, or ride sharing, has it ever been in an accident, and is there a documented service history you can review. Straightforward answers to these questions, backed up by paperwork where possible, tell you more about a used vehicle's true condition than the odometer reading by itself.
