Welcome to the jungle from New Jersey, USA, Mr. Casey! Having been born and raised in Shelby country, your Aston Martin would naturally sing to me more than Carrol's Ford.
Not meaning to be obsequious, however it is not a "TR3" that has caught your fancy,
rather, it is the R3T (Rocket III Touring) or the R3R (Rocket III Roadster) that is turning your head...
Given that you are clearly a performance oriented vehicle enthusiast, permit me to whet your whistle a bit further, with a sidebar notation that there's a fellow on your fair isle named Neville Lush that can deliver very similar goods to this:
