Used vehicles are hit or miss depending on how well they’ve been cared for and what kind of replacement parts have been installed during their life-cycles. Brands to steer clear of when buying used include Chrysler, BMW, older Ford models, Dodge RAM trucks, Cadillac, Audi, and Fiat. You should always check the vehicle history when buying used to see if there are any significant accidents or problems. Besides, you should always research the make, model, and year of the vehicle you’re interested in buying. Reliability and performance changes from year to year and some older models — and even some newer models — are worse off than others.
