McLaren's first customer based vehicles, the M12 was based on the M8As Bruce McLaren used to win during the 1968 Can-Am season. This 1969 McLaren M12 Coupe is part of that lineage, but has some distinguishing factors which make it uncommon. After entering several races in the early 70's, the car was converted into a coupe in 1976. The same owner decided to also make it street legal, making it a show-stopper everywhere it went. It's one of only 8 original road cars in the world and the only of those eight that is a coupe fitted with the correct Chevy big block V8 engine. The upcoming auction is a chance to own a rare piece of McLaren history.
