Oh yeah, give another vote for the Enzo as well. It looks like origami gone bad on automotive design! Blech!
As for the Ion I think its a huge improvement over the outgoing S-series. Although lets not kids oursevles here, who actually gives a flying rat's ass about the Ion? I'm surprised GM's trying to bring a "tuner coupe" to the market with 200+ hp. I mean, good idea, but I doubt the execution will be anything close to a success.
