I have used them (abc), for my freinds car which they did not even know was going to be an unmarked police car(no you can't have the reg number!!!).
The work done was total quality with care, a little late but not their fault, did have a problem, that WAS NOT DOWN TO THEM, but they put it right at no cost straight away.
This is my experience.

ps my "freind" will of course remain nameless, as the bizzys do not like me anyway.
