26. 1994 McLaren F1 LM
There’s much written about the F1. Car writers have discussed how it was designed and how it changed the supercar world forever. The F1 was introduced in 1992 and stayed in production until 1998. McLaren produced 106 cars during that period including the GT-R versions, which were highly successful racing models (via Motor Authority).

The F1 featured a bespoke 6.1-liter V12 engine made by BMW Motorsport, which delivered 627 HP and had a six-speed manual transmission. The example pictured is the ultra-rare LM semi-competition version, of which only five were built. Hence its insane price of $19.8 million as a result.
