Seeking Purchase Advice E70 X5 Diesel US

[notchuckie]

Hello Everyone. I'm new to the forum. I'm looking for advice on purchase of E70 X5 Diesel for use in northeast US as commuter and winter daily driver. I want to be able to add these options/features. What year(s) do you recommend that I look to buy? Thank you.

Paddle Shifters-Ability to add paddle shifters. BMW OEM preferred.
Remote Start-Ability to add remote starter. After market is all I can find.
Multi-contour seats-under thigh extension/support.
Head-up display.
Back up camera.

Please save me from looking at Jeep Grand Cherokee Diesel, and the Cayenne is very nice, but too much $$.
