I have been going to Tuning Grüppe for about 2 and a half years now. Eric and the guys there are very friendly, knowledgeable, and also honest with the work that needs to be done. They won't try to sell you a service/part if your car doesn't need it. Not only have they worked on my VW Jetta, but my wife's Infiniti G20, my sister's Ford Fusion, and my mother-in-law's Olds. Alero. I have also sent my friends there. I would definitely recommend them to anyone that needs a good shop for their car(s).
