We have an 2001 Audi S4. In the past it was always serviced at the dealership, but I have a close highschool friend who's parents own and operate a mechanic shop. They are very trust worthy and honest ppl, but they specialize in american cars. I was referred by them to get the car checked at Volx German. My mom reported that she was really happy with the service and that they were very respectful. She really trusts this place, and my mom is actually very mechanically inclined. She use work on her Volvo back in the day, and continues to work on cars, but only to a minimal maint level. The Audi is tough for her, because it needs a professional. Although the car has been going to the dealship in the past, they were a "headache", and "overpaid". I highly recommend this shop.
