Hang on — do you mean the cheapest? Because that’s an easy answer; the Ford Mustang Mach 1 offers 460hp performance and 4.8secs 0-62mph for £57,075. Of course, you may well consider that the Mach 1 is a bit crude and rugged to be included here and you could be right. So let’s consider value, rather than mere price. There’s one car here that offers staggering performance, practicality, style, and quality for less than some others. It’s the Porsche 911 Turbo, which is quicker to 62mph by half-a-second compared to the Aston Martin DBS, but which, at £143,000, costs £82,000 less.
