I am not American, but as a Canadian:
I find Astons to be nice cars on the outside and under the hood, but the interior leaves a great deal to be desired, even the more recent ones, with my friends 2011 Virage being one of the nicest looking cars until you open the door and sit in it.
I happen to really like Bentley's, I think the reinvention of them has been excellent and they have an imperial look to them.
I am, however, not a fan with Mclaren's, like the above, the performance is what you'd expect for the money, but the body designs just do not do it for me.
