I'm with G and W mainly for the same reasons that other TMers have stated but an additional factor is that they never quibble about the exact nature of the repairs and, as we know, because of the way trads are constructed, what might be a simple job on a modern unitary construction car can be quite tricky on Mog. I've talked to a number of dealers about this ( eg have a chat to Kevin at Tudor Motors) and they all say the same thing
regards,
G
