VOB BMW in Rockville will not honor any warranty,not unless its theirs! Secondly be very carefull when dropping of your Bimmer with them,they have some reckless dudes driving costumer cars. Inspect your car fully before you get to the dealer and note any scratches,any body damage. Once you get there,there will be a guy to look at your car,no problem with that.The problem is at the end of the day when they call you to come and pick up your car. That same guy who was there to see whether your car had any body damage is nowhere to be seen. Usually when VOB calls you to come and pick up your car it is evening, its dark, and you can't see that well.My 20" rims were scratched there and the shop never took responsability for the damage!
