WARNING: Do not expect to receive your X3 special order within the as advertised four week time period. My personal experience has been that an order placed on Dec 9 2010, with a substantial down payment, was not off the production line until 15 Feb 2011 (68 days). It is now 71 days and still no car. The issue was compounded by the loss of my 2005 X3 on Dec 6 2010 when I was hit on the driver side door by a red light runner at 35 mph. I had to rent a car at my expense for 58 days. The BMW dealer has lent me a car for the remainder of the time. BMW Customer Service is of no help and unwilling to offer an explanation as to what I consider is an excessive delay.
