Russel BMW worked out for us quite well last week (7/13). They even offered to have a tech ride with me so I could duplicate the problem. They ordered the left motor mount and had it fixed by the following Tues. Tom Wolff was a referral from WagnerX5 and he was great and friendly. Didn't have a BMW loaner, but that's okay. The Enterprise rental was a '07 Mazda3 2.3i sport in decent condition, something I didn't mind driving at all. Tom picked up the tab for 5 days' worth of rental.
At least Russel isn't overbooked and cramped as badly as VOB. After losing my service rep (he left), there is no reason for me to go there. They will only pay your Enterprise rental for one day. They dismissed my problem as "no problem found". The people that drive the BMWs in and out of the cramped service bay always have me worrying that they'll clip a fender or snap a mirror.
I've heard mixed reviews about BMW of Fairfax, thats why I'm hesistant to bring it there. I know they have a new service bay, but that doesn't change the service advisors' attitudes or the actual service itself. I think Sterling BMW has overall more positive feedback.
