Your mechanic doesn't do much work Porsches. I have used them a lot in the past when I had a Saab (which is ultimately gm/American technology), but now that I have a decade old Mercedes and a decade old Porsche (I prefer maintenance over deprecation). Once a your mechanic contractor called me after the meeting was scheduled to start and told me that they couldn't service the car because they had no experience, diagnostic tools or spare parts for my car, and other interactions with them weren't better. Another time, their suggested 'OEM' quality parts really werent.

Another factor might also be that many high end imports are services at the dealer/speciality shops and the service interactions with your mechanic are for cars that have less than stellar maintenance-- which skews the picture significantly.
