Its fapping quick!!
In real world driving you honestly don't need anything quicker!
I went out with a couple of friends last night, one in an M6 and the other in an M3 CS.
The comparison with the CS was the most interesting. Mid range the 335 eats it, I can imagine the CS will be quicker on track or on a demanding stretch of road but I think that gap will be reduced with a decent suspension set up on the E92....
Final thought on my new purchase....
I hope I keep hold of my licence long enough to make the most of it!
