5. Radical SR8 LM
Who would have thought that the Radical SR8 LM is actually street-legal? Even though it looks like a race car, you can drive it on public roads in Britain. While you cannot go full speed in the UK, on Nurburgring, the Radical SR8 LM unleashed its potential, finishing with 6:48.00, which is one of the best results ever. And to make things even more impressive, this was back in 2009.
