and I almost forgot! the dual personality of the turbo is just awe-some !!! That was actually the reason I bought the car - you can be smooth one minute and next minute you're rippin' it... actually, I think I'm gonna sign off and go for a drive in mine

 

i have a 4.2 and for a while was looking to upgrade to an e39 M5....i love the car but cant do it because of the subpar interior compared to the audi. i honestly believe the bmw has more personality/ fun to drive (rear wheel drive) but the audi is more comfortable and better looking. just my 2 cents....
