Camaro Jack!
This one comes from The Garage, and reveals that your car might be doing a bit more than just getting repaired while in the shop:
I had taken my then new 1996 Z28 convertible. The first new car I had ever bought in to have the rear bumper fixed.
Two days later as I’m driving around in my piece of crap rental car I look over while at a light and there’s my car. With one of the autobody repair guys in it and some woman. It’s about 8pm and I’m pretty confused as to why they would need to be driving my car around AT ALL let alone at night with passengers.
So I start honking madly and finally after several miles of this get the guy to pull over. Turns out he was on a date, and had put 67 miles on it, “testing it for squeaks or rattles”, oh and the NEW rear tires were almost gone.
