Just had a call from my SA that BMW is extending the 4500 Eco-Credit for 2011 X5's until 4/30 so anyone waiting for it to be announced it's official...

As a side note if you are thinking of ordering a new X5 and want to get a haggle free Costco price send me a PM and I will send you my SA information. He is the Mid-Atlantic rep for Costco sales but can place orders for anyone in the US and arrange for delivery (Highly recommend doing the Performance Center Delivery). Having bought my 10 X5 35d from him I can attest to his superb quality of service.
