Aww come on. I'm also not a big fan of mustangs but even the original GT500s have a ton more torque then any honda. And the Elanore remakes have really worked engines in them.
And your comparison really isn't that good. From what I know of those old V8 Astons they are pretty damn rare. I would bet you'd be spending quite a bit more then you would on a GT500.
You can't knock mustangs for not handling well. It's just something they were never designed for. But they go straight for a 1/4 mile pretty fast.
But I never realized how much those old Astons look like mustangs. I wonder who copied off who.

Torque is a silly measurement to go by as it is altered by the gearbox. Which as I said, in muscle cars uses a really short ratio so they have huge amounts of torque (quick off the line) but a low top end and that was more down to the limitations of the engine which had no real power for it's size and not through good design.
I will admit I do like how Mustangs look and sound, but like I already said you'd only ever keep one on your drive/in the garage to say "yes I have a mustang" but without a lot of work to the undersides you wouldn't want to drive it. I wouldn't anyway as round where I live is mostly winding country roads so I'd want a car that felt confident on them and American steering racks never had that. Even now when they get a rolling chassis from Mercedes Benz, they will take a great handling car and replace the steering rack with an American favoured one (not to mention replace the springs and shocks with marshmallows and elastic bands), which just gives no feedback at all. Maybe being "eurotrash" or a "eurofag" means I am spoilt for choice as I've done B-Road blasts in great handling cars and some appalling ones and I know what I'd rather have.
AMV8's have held their price well and you're looking at new Ferrari/Lambo money for one, however to get say an Eleanor over here you're not far off that anyway. But personally, I'd still take the AMV8. It makes all the right noises a V8 should, it drove better than the Ferrari's and Lambo's of the day and it was faster than the Ferrari's and Lambo's of the day, although not by much.
I've always been a fan of American Muscle, but not as a car I'd ever want to drive, just something to look at. Old Aston's just tick all my check boxes.
