For those in the Northern VA area, I found a great mechanic who specializes in only BMWs. Alexandria Bavarian is the name...right off Rt. 1 by Potomac Yards. I'm getting my tires mounted there tomorrow for $136!!!!!!!! Insane!!! And he doesn't use that Hunter machine for mounting that scratches the rims...he's got the machine that BMW uses. BMW of Arlington quoted me $440 for the mount/balance and they said they would only do it if I bought the tires from them. Pitiful. I'm sure I'm coming into this late and many of you already know about this shop (Grant Randall is the owner and guy you should speak with www.alexandriabavarian.com), but for those who don't...I hope this helps.
