When you are buying used, the brand on the trunk is the single strongest predictor of how much the car will cost you over the next five years. Two cars with the same mileage and price can have wildly different ownership costs depending on how reliable the brand is, how expensive its parts are, and whether any mechanic can work on it. Here is how the major brands stack up for used buyers.
Japanese brands — the reliability benchmark: Toyota, Lexus, and Honda set the standard. Their conventional powertrains routinely pass 200,000 miles, parts are cheap and available everywhere, and any independent mechanic can service them. Mazda and Subaru are close behind, with two cautions: some Subaru boxer engines have head-gasket and oil-consumption histories worth checking by year, and Nissan sits lower than the others mainly because of its widespread, failure-prone CVTs. For lowest-risk used buying, this group is the safe default.
Korean brands — the value play: Hyundai, Kia, and Genesis have closed most of the reliability gap on recent model years and offer strong value. Parts and service are affordable and widely available. The main things to check are the specific engine (a few Hyundai/Kia four-cylinders had oil-consumption and engine-failure issues on certain years) and how much of the original long powertrain warranty transfers to you.
Domestic brands — it depends on the model: Ford, Chevrolet, GMC, Ram, and Jeep are a mixed picture. Their full-size trucks and proven V8s can be extremely durable, and parts are cheap and everywhere. But some domestic transmissions and electronics are weaker than the Japanese equivalents, and a few specific models have well-known problem years. Domestics reward model-by-model research more than brand-level trust.
German luxury — great to drive, expensive to keep: BMW, Mercedes-Benz, Audi, and Porsche are superbly engineered, but that engineering comes with proprietary diagnostics, specialized labor, and expensive parts. A well-maintained German car can be reliable, but the cost of keeping it that way is far higher than a comparable Japanese car, and deferred maintenance gets expensive fast. Volkswagen sits just above this group on cost but still often needs brand-specific diagnostic tools.
Why brand matters more than badge appeal: Reliability on the used market is really about three things: how often the car breaks, how much the parts cost, and whether you are locked into a dealer to fix it. Brand reputation captures all three at once, which is why CarScorer builds a brand tier directly into every score — a Japanese brand earns a repairability bonus, while German luxury carries a penalty for its ownership cost. Brand is not the whole story, but it is the best starting point.
