I think this happened to my car once... Dropped it off at Ultra tune for a service, the place was recommended to me by a friend, said they do a good job bla bla bla. Anyways I didnt take note of how many kays or anything on the car, when I go to pick it up, a few of the guys working there had smirks on there faces, a couple of them commented on how 'nice' my car was... Didnt click till I left.. You know when ya give ya car a floggin, and I just feels 'loose' like it just wants to go, that's what it felt like... Have never been back, not even to stamp my log book..
