I guess this car actually doesn't fit here whether it's an one-off prototype... if so it is possible to add Lambo Sesto Elemento or Ferrari SP12 EC, they're also one-off prototypes and are sold, as far as I know.
But, Goddamn, this Aston has 700 hp!!! Even nowadays it's pretty a lot, but in 1980 that was just... something otherwise! Damn, what transmission is here used that's able to withstand that insane torque in a "road legal" car in 1980?
About its design - it's damn impressive, but at the same time strange in the bad way... One word describes it the best - extraordinary.
Is anyone going to claim it looks somehow reminding modern Astons? :D
It extremely reminds me Countach. Bulldog's design was obviously inspired by the Lambo.
