Its a '97 NSX-T.
My brother had a real "bad" 328ci a few years ago, and he decided never to buy a BMW again, or else I'd tell him to get an M3.
The wheels are the fugliest thing on the car. He's for sure going to upgrade to some nicer wheels if he gets the SC430.
He test drove both last night (both auto's) and said the s4 did not seem THAT much faster than the SC430. He's leaning towards the SC430.
If he gets the SC, it will look something like this, basically some soft mod's like wheels and intake, etc.:
