2. Marcos Mantis XP

Based on the Marcos Mantis street car, which was almost as bonkers, the Mantis XP was built for the 1968 1000 km event at Spa, where it retired with electrical problems in heavy rain.
Originally the XP was meant race in Le Mans, but by that stage it had made its way over to the States and had been fitted with a big ol' V8. A full restoration of the XP was completed in 2008
3. Jaguar XJ13

A prototype built for Le Mans in the 1960s, the car never actually raced. Someone at Jag thought it would be a good idea to use the XJ13 in a promotional video for the new E Type. During filming, a rear tyre deflated at speed, the car rolled heavily and was nearly destroyed. After the crash, it was put into storage.Some years later it was restored at serious expense to Jaguar.
4. BMW Z4 Zagato
The launch of the 2012 BMW was a massive leap forward, in terms of design at least, for the German Marque. Thing is, the standard Z4 was left looking like a pale imitation when BMW teamed up with Italian design house and coach-builder Zagato to build this one-off masterpiece.
While the car's unmistakably still a Z4, Zagato's signature additions make it look immensely desirable.
5. Ugar Sahin Ferrari
This is one-off from Dutch design house Ugur Sahin.
