It really pioneered the market on high-performance SUVs with the intro of the ultra-badass 4.6is, basically the first X5 M, and later with the high end 4.8is. The early styling was really aggressive, and its probably safe to say its THE best looking SUV on the road. The interior is filled with every amenity one could want (my 02 3.0 has satnav, bluetooth, roof, cold weather, and some other sick options) and is really luxuriously sporty. The steering is spot on and the handling behaves like a 5, niiice. The bimmer straight 6 is a work of wondrously brilliant engineers and puts some pointless redlining fun into doing things like pulling out of target, merging, etc. DON'T bother with the X3 as you will be missing out in what its big brother has to offer. The X5 is a beautifully crafted work of pure german automotive genius.
Me: Well you can go kill yourself you ignorant fool as the X5 is none such things. The truck is a work of automotive art, like a Maserati Ghibli, or Ferrari 288 GTO.
