The BEST!!! Hands Down! I have a 2003 Audi A4 3.0 Sedan. I took it in here after just moving to Raleigh NC from Phoenix AZ. My car needed some repairs after a rough noise was under the hood. These guys had an answer for me in moments as to what the problem was. They gave me an estimate, and worked with my extended warranty company to complete the job. They not only came in under the estimate (even after working with my warranty company who picked up the entire cost) they actually appreciated my business. It's hard to find quality people to do anything for you in the service industry, but these guys ROCK! I'll be taking my car here even for simple oil changes and my girlfriends VW Jetta as well!
