There is nothing about the McLaren F1 that can't be described as legendary. The brainchild of Ron Dennis and Mansour Ojjeh and designed by Gordon Murray, the mission was to build the ultimate road car, with McLaren hitting their mark so perfectly that the F1 is still a force to be reckoned with nearly 30 years later. Of the 106 F1s built, 64 were road cars and five were built to LM specification after the F1's overall victory in the 1995 24 Hours of Le Mans. The F1 pictured here is a 1994 model that was returned to the factory in 2000 and 2001 for two rounds of modifications to bring it LM-spec. The BMW V12 was retuned to 680 horsepower and an aggressive aero package and massive rear wing added, along with being repainted in its current silver color. Only two F1s were returned to McLaren for these modifications, making this one of the best of the best. The car comes up for auction in August in Monterey with a price of over $20 million expected.
