I had my car worked on here once before. The work was okay, I guess, but they never could figure out the engine light problem. It was expensive, and although i know Volkswagens are expensive to work on anyway, I feel like it was a bit too much. I have also had a friend tell me that they overcharge for their services.
They're awfully nice about it, though.
Edit: 5/18/06: Had more work done here the other day because they are so convenient. Fast, efficient, and they did not push anything I did not need.
