Yea, the 4.8 is sick. I personally prefer the rims from the 4.6 and when we picked up our 05 4.4 we actually managed to switch rims with a 4.6 as part of the deal, then the salesman realized he would get fired for doing that being that they are special wheels only for the 4.6 I could have told him that, but I wanted to see the outcome. But we ended up getting nicer rims than what we started with anyways, so it all worked out I guess.I want to do up our 4.4 like the 4.8 The small differences really do make a large impact. I like the euro lights too, but unfortunately that's no simple matter of replacing reflectors. You have to buy the entire damn assembly which I am sure is not cheap as not only are they auto leveling bi-xenon, but they are also adaptive headlights.
Our X5 is great. It is a very fun car with plenty of power. Handles very well, and I'm sure, for the type of car it is, it's pretty high in its class. But personally, I kinda miss our Suburban. I love riding in my friend's 06 XL Denali. They are just very comfortable, spacious, nice SUV's. Especially good for long trips and hauling lots of crap and people. The X5 is nice, but obviously it is a lot more sportier, and with the short wheelbase and stiff auto-leveling/height adjustable sport suspension it rides, well, like a sports car. Not nearly as cushy as a Suburban, though that was to be expected. Not nearly the same car.
