I was in the RS4 for the Audi event as well and that car is fast as hell. What impressed me the most is the Sports button that completely transform the car into a big shouting beast. The exhaust note is pretty intoxicating and the adpative suspension protects the passenger from the biggest potholes in LA. Clearly the RS4 is the faster and more technologically advance car compare to the current M3 but it's also 5-6 years late? Compare to the new M3, pricing wise, the M3 will be a bargain.
Oh guys please resize those 5 series photos. I think I am going to go blind looking at those feline headlamps. Bangle sucks. If I have one I'd tint the windows so no one knows I own such an ugly car.
It's E92 M3 all the way..
