Summary: good for general service, technically inexperienced otherwise
Pros: friendly people, drives you to/from Metro stop even outside scheduled times, didn't wait long for appointment
Cons: didn't know problem that other dealers knew about (charged me anyway), suggested additional work (+charge) that should have been part of maintenance
Went in for: 1-30,000 mile maintenance, 2-headlight aim check
Costs (total-$460): 30k maint-$260, brake fluid change-$140, headlight "check"-$60
They probably did the 30k just fine; nothing's come up so far. They called me an hour after I dropped the car off to ask if I wanted a brake fluid change, which VW recommends every 2 years and they noticed was "probably not done". It was $140. I disagree with the recommendation, but my car is a lease, so I called them back and okayed it. They called me a few hours later to tell me that car was ready and even picked me up from the Metro stop after their regular transport hours. Driver was nice.
However, task 2 they didn't do so well. My 2007 GTI(which has Xenons) was in a front-end collision and when a different shop repaired it, they didn't aim the headlights correctly. The beam pattern is off and I'm regularly high-beaming whatever car's to my front right. 2 other dealers ( in Detroit MI and Pittsburgh PA ) said that this was a common thing and easy to fix. I'm on a roadtrip, so I didn't have time to get it fixed at those places and thought I would ask these guys. They looked at it and didn't know what was going on. Decided to charge me $60 anyway. My headlights still don't project further than my foglights do ( ~10 feet ), except to high-beam the car next to me.
