4. Bugatti Centodieci – £6.5m

With this supercar, Bugatti pays homage to its 110-year old legacy. The word ‘Centodieci’ means 110 in Italian. The car is equipped with an 8.0-litre W-16 engine capable of producing a staggering 1600 horsepower. It can accelerate from 0 to 62 mph in just 2.4 seconds, making Centodieci the quickest-accelerating Bugatti currently on the road.
The design of the car is heavily influenced by Romano Artioli’s iconic EB110, a supercar produced in the early ‘90s. Without losing the charm and character of EB110, Centodieci is designed to serve as the modern interpretation of shape and technology.

3. Rolls-Royce Sweptail – £10.2m

This list is full of limited edition cars, and the Rolls-Royce Sweptail is no exception. This one-off car draws inspiration from the finer things in life. Giles Taylor, director of design at Rolls-Royce Motor Cars, described the Sweptail as “the automotive equivalent of Haute couture”.
The Sweptail was also inspired by the coach building of the 1920s and 1930s, and was commissioned at the request of an aircraft and superyacht specialist who had the idea. Costing £10.2 million in 2017, at the time it was finished it was the most expensive car of all time. In the years that have followed it has been supplanted by the Bugatti and Pagani listed below.
