Fantastic service. I have a 2004 VW Passat. I take it here exclusively. Dave and his team does great work. They explain very well their recommendations and always have good communication throughout the repair/maintenance process. I highly recommend for VW vehicles. They know their stuff, and won't take you for a ride.
