I finally put in the order on my X5 with the configuration below, but I'm going to make one change that I could use some input on - I'm either going to add the comfort seats (at minimum) or the Active Ventilated seats. I've seen some good feedback on the comfort seats, and tried them on my salesman's car, so I'm definitely adding those. So, my question is for anyone who has gotten the active ventilated seats - Are the active and ventilated features are worth the extra $$ over the comfort seats?

Here's what I ordered, set to go in the April production (dealer had one on order that they were able to modify for my configuration):

4.8i Black Sapphire with Black leather and dark bamboo
Sport Package
20" Y-Spoke Wheels
Premium
Tech
Comfort Access
Rear Climate
Cold Weather
Heated Rear Seats
Premium Sound
HD Radio
Sirius
iPod Interface
Running Boards
Tow hitch (dealer installed....)

To add: Comfort Seats or Active Ventilated Seats.....

Thanks for any insights on the seats!
