The bottom line
These cars often arrive with extensive prior panel work and more structural repairs than the typical used vehicle, paired with frequent engine oil leaks, cooling issues, error codes, worn tires and steering leaks. Start your inspection under the hood and chassis looking for oil and coolant problems first, then pull codes and check the tires and power-steering fluid. High bodywork rates mean treat the paint as suspect and look closely for signs of previous structural work; walk or negotiate aggressively if you spot several of those faults. They hold decent condition until roughly 121,000 miles, making lower-mileage ones the safer play.
