Thank you for all the replies. I am taking the car to have it inspected by a mechanic tomorrow and see if they can spot any problems. I (and my husband) have looked this car over from top to bottom, inside and out, and can't spot any evidence of a paint job or any other damage (other than the AWD emblem being missing). If anything has been repainted they must have done a very excellent job, as there are no traces of imperfection that I can find. I am just super confused at this point.
