The ugly bonnet as you put it, is rather necessary to house the super charger though.
They actually look a lot better in person, not a very good shot but this 350 belongs to a friend of mine, who's running the full Stillen setup, he's had over 20,000kms of full race driven kms, being driven at full throttle the whole time. This photo was taken almost 2 years ago.
One thing I've noticed with his car, obviously being a full blown race car the bonnet is up and down every pitstop, the bonnet is looking a wee bit tired in a few areas.
