Jayjay - i know that:), i mix everything for my X5 because i treat this X like my toy, the important thing that i like what i did. There are alot of people put their 3.0 to sport wheels (4.4) to make the X looks stronger and nicer. There are alot of ugly parts that made from X5, 3.0 tips is one of those ugly pieces.
This X5 is cheap price ($17K when i bought with 47K miles, 2004) and feeling good if i can mod this X by myself (most mods were made by myself). If it wasn't cheap, i didn't buy this X instead of looking for a Mercedes Benz GLK class or R-Class. We love MB because we have driven MB for 4 years without any tiny problem.
