This is BS and happens more than any of us know. The first link is evidence that it happens with video. The second two are other suspecting post. I have no doubt your car was taken for a joy ride. The only thing you have going for you is your car is strong and can handle the abuse that they gave to it. I have always done the no wash..... I will now add, no test drive. Hang in there.
