Hullo I have had a 2004 XK8 for a couple of years. I love it to bits but garages don't. I took it to a garage a few weeks ago with a couple of problems and it came back with more. The garage I used previously wasn't much better. I can't help thinking that I need a specialist. I don't particularly want to go to a main dealer. I live in SW19 but I spend a lot of time near Guildford. Can anyone recommend one? JBJ
