Just thought I would throw another option in there for you mate.
I just had my classic serviced today at 'Riddles Garage' in Bo'ness which is a family run buisness. I would definitely recommend these guys. Both brothers have owned Jap cars which were both minted examples - one a classic impreza (which is now mine :-) ) and the other an Evo - so they both know the passion we have for our cars. My car always goes there and I have seen a number of Imprezas in there.
Happy motoring
