What involved responses. Well, I too read about the Mosler MT900, and I agree that its numbers are fantastic. Warren Mosler is a body designer without equal (just imagine if he'd been able to make the MT900 with the Raptor split-window windshield that Trenne simply refused to allow the MT900 to be produced with - perhaps the numbers would be even more staggering). Seems to have absolutely no short-comings... but I am just not stirred by its design the in the same way the S7 makes me feel. But I agree with your commentary 100%
However, if I failed to mention it here, the be-all end-all sports car in my book is the Koenigsegg CC. Here's some more info on it (note 0-60 = 3.2 seconds, top speed = 242 mph, curb weight = 2,425 lbs.):
