I agree, i went from a e92 to a S5 now going back to M3. The audi is perfect into a corner, almost refusing to let go.
but the M3 is wild fun. I will miss the refined and beauriful S5 but the M3 is sex on wheels for driving. i was waiting for Rs-5 but no stick shift. Something about having a big solid shaft with a big nob on the end turns me on.
