These are 10 of the worst supercars ever built

This Swiss monstrosity promises 900bhp and a top speed in excess of 260mph. Just two problems: no one's ever actually driven one, and it looks like a nightmarish Tim Burton interpretation of a BMW Z4. The horror!

Looked like a supercar, went like a lumbering old Metro. With a 130bhp Peugeot V6 instead of the optional flux capacitor, the DMC-12 was woefully slow: catalytic converted models took 10 seconds to crack 60mph. And couldn't fly.

Denounced by one J Clarkson as "the worst car in the entire world", the M12 was a rebodied Diablo with the sophistication of a mastodon and the build quality of a Glastonbury tent. Made the Lambo look like a sensible, reliable choice. 

Billed as an ‘F1 Car For The Road', the 575bhp Caparo can do 0-100mph in five seconds flat. Problem is, most of the time it won't, preferring to be broken or substantially on fire. Or both. Scorching performance at its worst.

Inspired by the Tyrrell P34 (the F1 car that Jody Scheckter called 'a piece of junk') the Panther had an 8.2-litre twin-turbo V8 and a claimed top speed in excess of 200mph, a claim never substantiated. Difficult to understand why.

Not to be confused with the 400 Superamerica of the 1950s (which was ace), the 400 was a bog-awful pretend GT and the first Ferrari with an auto' box. Designed to woo lazy Americans, it never went on sale in the States. Oops.

Conceived in the booming mid-80s but released in the depression of the early 1990s, the Virage was average to drive, shoddily built and, despite costing £120,000 (over £200k in today's money) had headlights borrowed from an Audi 200.

Inspired by the Honda NSX but nowhere near as fast, attractive or acceptable, the 230bhp Orochi resembles an aroused bottom feeder trying to suppress wind.

Not an awful car in its own right, but suffered from its billing as the useable, affordable alternative to the Countach. That's like trying to make a living as a friendly, vegetarian mako shark. Or a prudish porn star. Or Nickelback
