If you were fairly tall and well built, had no kids or dog, had no qualms about fuel or insurances prices, enjoy power but do not want a dong extension, what car would you get?
You don't have to spend a load of money to get a car you like.
My favourite car ever was a BMW 525i. It was a 1985 model and was already 11 years old when I bought it. It was my world..a fabulous good-looking car and great to drive.
The Ultima GTR flaming well IS a production car, look at the second paragraph of the company's website. It'll cost you about �80k if they build it for you (near Leicester). They cannot claim world records unless they meet stringent requirements. And it goes like sh!te off a shovel.
I borrowed a Citroen 2CV once...............with a stripey top...............Citroen Deux Cheveux...............but it couldn't handle Deux builders in it................chassis collapsed...... :o(
