I know it happens all the time, my cousin works for Audi and he rips customers RS4's day and night.
My mum took her new VW in for its first service the other day, no problems with it - just needed oil and filters etc. However it come back with 15 extra miles on the clock. Obviously there was no need to test drive the dam thing. The lease company have told her that if the garage can not come up with a good explanation they will lose their business (800 cars a year). Pretty annoying really though - Prolly went to pick up lunch in it
