I'm looking into puchasing a used one. Not the turbos but just the base model or the S model. My only concern is a lot of the used ones have well over 70k miles. Most are closer to 100k and up. I know any car is reliable if taken care of, but ford vcm 2 there are those cars where things just go wrong left and right after a certain number of miles. Is this the case with the Cayenne? Are there problematic years or trims or things I should look for that are specific to that car?
