wow seems like you need some help! Just like X-tra said go on Bmwusa.com you can find all you need there, and leatherette is a material that looks like leather but is not as nice. I just bought a X3 3.0 with leatherette , i had a choice of a 2.5i with leather or the 3.0 with leatherette and i can say im a hell lot happier with having the 3.0 engine with leatherette than the 2.5. And about the clear lights. The '04 X5 now has the cleared out lights. You just need to do some research and go to a bmw dealership and ask them some of the questions you have. Trust me their not like American or Japanese dealerships where they put u in one corner and try to sell you a car. Good Luck!
