Doward, I would agree with how awesome the Esprit is! I love that car!! Just not too fond of the motor and trans, but if that was different then it would get my top vote.
I like the idea of the variable geometry turbos but doesn't seem very tested. Corky Bell is a pretty smart dude but I've seen way more impressive setups with fixed turbos. Google Bob Norwood sometime.
Swaq brings up a couple good points though. The Noble derived cars are awesome! I have a buddy in Glenwood Springs that let me tool around in a M400 and wowsers! Also Bugatti is a great example of awesome turbo cars. The EB110 was a sick car and the Veyron is pretty intense too.
