I put around 10k since i got mine and to honest I sure do have little problems here and there but gosh I love the X. the car is amazing, i love the body the most to be honest and the drive is great when the tranny doesnt bug out. I got my 01 X5 4.4i at 112k and shes at 122k today, and she still runs like a beast..... X's are the best.

And to be honest I really don't think they die. Ive seen an X5 with crappy maintenance, the car drove like shit and it ended up killing the engine with 103k on it, the car didnt have an oil change within years of the driver driving it. he abused the crap out of the car. and on a side note i have a friend who owns a 2000 X5 and he has over 418k last i checked, he changed his transmission once and after that for him its just brake pads, rotors, oil change and I THINK he changed his water pump once? not sure on that one.....
