Does anybody know of a good independent repair shop in the Dallas/Fort Worth area?

Without the dealership prices!

 

Southwest Auto is pretty good... and they know a lot about all Volvos. They helped me out with my 1983 242 non turbo, it runs fine now.

you may also wish to try Dave's Foreign Auto service in Denton, TX. I have been taking ALL of my foreign cars to them for the last 12 years, and never had a problem. Very professional, dont over change, give away free work often, always happy to answer questions over the phone. If you can get there, I highly recommend them.
