I just placed an order for a 2010 X5 35d

Black Saphire Metallic / Black Leather
Premium Package
Running Boards
3rd Row Seat
Park Distance Controll
Rear Seat Entertainment
Roof Rails
20" or 21" future OEM wheel upgrade (not decided on style yet)

I really wanted the sports package, but I cant believe they changed the option and seperated the Adaptive Drive as a standalone option. THIS FREAKIN SUCKS!!!!!!!!!!!!!!!!!!!!!!!

Because my wife has me on a budget, I am forced to choose between the following options.

$2200 Sport Activity Package
$3500 Adaptive Drive
$1200 Multi-contour seats

I though about getting the Sport Activity Package, then lowering my X5 in the future with the H&R springs and links for the rear. Will this improve handling??? I know it probably will not make it as refined as the Adaptive Drive, but will it make it close? I could also appreciate the looks of a lowered, more aggressive stance. I have H&R springs and Bilstein Shocks/Struts on my CLK 500, and that made a load of difference on looks and handling.

Multi-contour seats would be nice if I chose to not get either of the other two options, regular seats are too bland. Probably won't be goin this route.

The most expensive and seemingly important option: Adaptive Drive, that sports suspension just seems so important with a Bimmer. But if I do this, I will be stuck with regular seats. Are they so bad???

PLEASE HELP ME DECIDE, and share your opinions.
