we've had several experiences with the marqueen garage and all of them have been surprisingly positive. they seem to be able to repair/tune up any sort of car (but i don't think they do body work) and do it quickly. and these people do NOT rip you off. my friend had a broken timing belt and they told her that the belt may have caused valves to blow, that they'd check into it. the next day they called and said "you're in luck, it was just the belt!" and that was it, car was ready.
and they are perfectly nice to deal with, too. located at the top of queen anne next to 5 spot.
