Good questions Grady. I think the type of shop is a very personal decision and the likes will be as varied as the colors of our cars. I value honesty and knowledge of product as most important. I tend to like smaller shops where you can talk directly to the tech working on the car. Since moving to Seattle, I've been very fortunate to have John Walker work on my car a few times. The guy knows 911's inside and out, won't BS you and always has something new/interesting in his shop to look at.
