The fact is that most “specialists” are poorly trained mechanics with a decent scan tool who get bigged up on forums by their mates / impress everyone with fancy pictures of their work, but don’t really know what they’re talking about
This is why I stopped using them. One asked me if my E39 had air conditioning - this was at a time when the E39 and E46 were the staple diet of specialists. If you don't know they never made one without it, how can you call yourself a specialist rather than just a garage with some good pictures on the wall?
