Similar story at my local dealers I'm afraid. Left the car in for warranty work on the turbo and when I picked it up there was a nice, deep 3inch scratch on the driver's door. Got them to check the damage report and they then admitted fault. Booked it in for paint correction which they then botched, so got a full respray on the door out of them.
Next time in the garage I had just fitted my brand spanking new 18" Zolders. Mechanic drove teh car into the ramp rather than onto it, and scored them. They agreed to pay for refurb, but did a half-arsed job. Fed up with them now though. Now using another dealer 15miles away instead of 0.5miles away, and alloy will be going to A1 in the next few weeks, along with another I kerbed, for a full refurb.
