Well, the truck looks 100x better with the lower/more aggressive stance IMHO, but also remember that there is (I think) the added benefit of much less body roll when handling corners with a lower ride height. I use my x5 on lots of narrow winding roads and never take it off roading, so the closer it is to a sedan the better for my purposes.
