No Astons don't look good, I've never liked the way they've looked, ever. I would much rather have the SL65 AMG because it would simpley be awesome to own something that powerful and looks better then the Aston. Plus I wouldn't have to drive around a British car (I'm sorry I just wouldn't drive a British car...maybe a TVR but that's a maybe).
I still hate Jags and I wouldn't ever buy one, you can get a perfectly good Benz or BMW which is better in everyway.
And GM doesn't make a GT eh?
If you consider a 2 seat roadster a GT car then this would be a GM designed and built GT car I would think.
But what's funny is you classify the Ford GT a GT car while it's not a convertable roadster, but a mid engined sorta race car and a Z06 is a supercar? I think they both are low end supercars.
And the Astons are all the exact same car with different engines. Seriously if you lined them all up I couldn't tell you which one was which.
