We have a 23 year old Saab 900S that Chris Gorecki has taken care of off and on since 1994. While Saab parts aren't cheap, we have never had a major problem or return for corrected work with Chris. He also won't fix something that he thinks is still serviceable, unless you tell him you are going overseas and just want to be sure.
Pros : Honest. Knowledgeable.
Cons : Get an appointment to bring in your car. He has a very small lot (although moving to SW Fort Worth) and there's not much room to just drop off a car.
