I picked up my X5 E70 3.0SD three months ago. I used to have an 645ci before and an X5 E53 before that. I have to say being used to the speed of the 645 I though I would be disappointed by the X5, but I have to say the SD goes like the clappers. Especially after I had it remapped at Jason's, the car does 0-60 in a very respectable 6.2sec!!!
I do have some plans for minor modifications to it. So far all I had done was the Remap, and just had the paint restored by a specialist. After the restoration, the carbon black really pops out.
Below are some pics of Xena (that's her name)
