German Auto Center has the best customer service of any place I have ever taken my car. Their techs are the best - they really know what they're doing. Sometimes I'm not very good at articulating problems and their techs have so much experience they can always figure out what's wrong and get it fixed. I know they will be fair with me and I have come to rely on their advice and service. I have found their prices to be better than the dealer, and the customer service is unbelievable. They will take me to work and come pick me up when my car is ready, so it's never inconvenient - sometimes they have even provided a loaner car for the day when I had some appointments while my BMW was in the shop. The business changed hands last year and the new owner has a really high standard for customer service, and it shows throughout the company - everyone goes the extra mile. I highly recommend them for any kind of repair or routine maintenance on Mercedes, BMW, VW, Audi, Porsche and I think they even work on Jaguars.
Pros: competent techs, convenience, very fair pricing
