i know what you mean
im sick of idiot machanics in my area so i dont use them now
i took my car in for a cambelt change and the other bits and the idiot that did it scratched all the wing loads of times where he was working because he didnt put anything over it,
and its my word against his he wont take the blame for it and said for me to just put some polish on it
This happened to me at a VW dealership when I got my cambelt and service done and when I pulled them up about it they said they were there when they started, they even showed me the job sheet and it stated that it had a scratch (singular, which I knew was there before I went in) but the mechanic had left loads of scratches where he had been working. The manager told me it wasn't their fault but would get the valeter to put some tcut on it, which i refused.
I'd like to say I never used them again, but, I bought a car off them and that turned out to be my biggest mistake. It had been in a smash and poorly repaired before I bought it and they didn't tell me, which I found out 2 days into ownership. I did get my money back though.
Complete cowboys, I doubt I'll use a dealership again.
