Ten years later, the liquidators of Marlborough Carpets found the car behind a bricked-up staircase at the company's warehouse; it has just 11 miles on the clock. However, given that a low-mileage example of this limited-edition supercar fetched just £85,000 at auction in Geneva recently, this ultra-low-mileage car has been valued at just £100,000, according to The Times.

The XJ220 was the fastest production vehicle of its time, until the launch of the McLaren F1. It boasted a top speed of 218 mph and a 0-60 mph acceleration time of 3.8 seconds, thanks to a 3.5-litre twin-turbo V6 engine producing 542 bhp and 475 lb ft of torque.

It was intended to be Jaguar's answer to the all-dominant Italian supercars, but didn't really take off, and less than 280 were made. What a waste, however, to hide one in a carpet warehouse for ten years... and its owner didn't even get to drive it.
