I'll give you some advice, avoid Fisher Buggies! I have never heard one good thing about any of their mechanical work since I've been into VW's (roughly 14 years). Just buying parts from them was a hassle sometimes since they didn't know much about Type 3's, which is what I have. Also, avoid the VW shop on Fletcher and 22nd (I Think), in the USF area. That guy is a complete tool and ripped me off once.
Total Performance used to be good, but I'm not sure if they are still in business. I know there are few other smaller shops around, but I can't think of any names right now.
