How much of a used car inspection do you spend sizing up the seller? I mean private party sellers, not professional used car salesmen. Have you walked away from a good looking car because something about the seller didn't feel right? Conversely, have you taken a chance on a less-than-cream-puff because the seller seemed on the up-and-up? When do you believe that the AC just needs a charge?
