i agree w/ucf3 that there are quite a few differences b/t the two cars. the sc400 is so much more heavier, plus it lacks the advantage of the steering wheel shifters (which r really cool :) ). and yes, i took the is and sc out on some of the worst country roads in KY and agree that coming out of some killer turns, the is would have blown an sc out of the water. but when ur racing from the intersection line when the light turns green, id rather be in the v8.
