Also, the chief mechanic, Lindsey (Lindsay?) at Little Foreign Car Garage in Belmont has a 2002 of some vintage. LFCG does not specialize in only BMWs (lots of Porsches and other foreign cars, mostly European). I am thinking of them only because of Lindsay's knowledge from his personal car ownership.
