We got our X5 4.8 about a month or so ago. We love this car! we also have a 330i and a 135i but the X5 is quickly becoming our favorite vehicle. It's the perfect combination of luxury and performance.
Quick back story: My GF is the parts and service director at a dealership. She got an '05 X5 4.4 to use as her daily driver. It was kind of beat and the sun roof wouldn't close on it's own but after about a month, we liked to so much we decides to buy it for 10k... a pretty good deal. Well while we were away for the weekend they sold it on her for 19k to some poor soul. They felt bad so they gave us their credentials for the dealer auctions. Thats where we found the 4.8... Palm Beach Fla. and had it shipped up.
We've added black grilles and hood vents, rear bumper step protection, NI-NOC'd all of the wood interior, added a phone holder and full cargo are protection cover. rubber front mats, replaced wheel center caps, replaced angel eyes bulbs with LED bulbs and replaced rear roundel
Maintenance done so far: power steering return hose, coolant expansion tank front control arm bushings and in the process of fixing the air suspension hell: replaced all of the air bags and still working out other air suspension issues.
I'd like to say that we wouldn't of been able to do a lot of this without X outpost. We are members on several BMW forums... some of them are pretty bad. This site seems to be one of the best and the members are very helpful and respectful without any flaming. That is very refreshing.
Here are some Pics:
