I think about it sometimes although I have not driven 5.0 yet. The whole X5 buying process started when we were looking for a car for my wife. She loved the 4.8 and I almost got one with the M pack. But then I found out that they were changing out in March and did not want a car that would be essentially completely revised in few months and costs 75K. Test drove the X5M and I was done with it. But it became my car, wife still needs a car and she is not happy with me. Had the 5.0 been available at the time, I probably would have gotten that for her
