BAC Mono at Isle of Man
 

Our editor who got to drive the Mono said it made him understand what a race car for the street actually was. And while I could have used a lot more in-car footage here, it's still pretty cool...

I think if I were going to go for the totally insane race car for the street route? I'd actually go with a Radical or Ultima GTR. Because I like being able to take a passenger. But for a track day? This would be the best.
