McLaren did various special editions of their car including 5 F1 LM, a prototype, 3 F1 GT and 28 F1 GTR. Koenigsegg is a beautiful car in my opinion, but the McLaren is just epic.
Edit: My idea was to point out that McLaren actually made a total of 100 cars not counting their prototype
Edit edit: Whoops, the F1 GTR wasn't a road legal car - my bad!
