For your EW, shop around various dealerships, knowing your in Northern VA, there is alot of BMW dealerships around. I called around 5 in the vicinity of my area. Only 2 were willing to negotiate the Extended Warranty price lower, I got about $400 discount on Platinum EW. Ironically one of the dealerships sales managers is my cousin's close friend. He said we don't discount EW prices. Sure you don't.
