which part of London?
I've used Hughes Coachworks (in West Molesey, near Kingston) a few times and they do a really good job. They are also the
garage the local
Seat dealer use.
Just got my car back today from Waldeck Bodyshop near Hounslow...they aren't anywhere near as good. I only used them as it was under warranty from work they did through my insurance a couple of years ago.
