BimmerDude 8 tenth of a second is not a good reason to pick a 4.8is over a 4.4i. My 01 4.4i feels stronger and faster than my fathers 06 4.8is. I have driven it several times in the last couple of months and I don't like the feel of valvetronic. Don't get me wrong it is brand new and looks awsome. I will most likly buy it from him in 5 or 6 years. But for now I love my 01 X.
