Just test drove the x5d. I took a nice corner and off ramp. Overall, I was pretty happy with the standard suspension.

Power wise, I though the acceleration not as responsive as I thought it would be, but I may be a bit spoiled since I have a 335i which is a lot lighter.
At 80+mph, I'd say if my 335i was a sprint, this would be a nice jog in terms of acceleration.

Thanks for all of your help! Now to figure out a price. If anyone has thoughts, the MSRP is $70k. They are offering it to me for $66k (after taxes and $4500 rebate).

Is this a good deal?
