There are good repair shops. But I think its car specific. I have a 930 Turbo, and a newer Subaru Sti.
I have a great Porsche Mechanic, good prices (relative to Porsche) owns a 930 Turbo himself, has access to used parts for this model that noone else has. Which saves money.
But if a coworkers Minivan needs new brakes, I wont recommend him.
My Subaru gets most of its work done in Squamish
