Any McLaren F1 is a unicorn, but the ultra-rare F1 LM-Specification cars are unicorns among unicorns. How rare? Only two were ever built. On average, ‘standard’ F1s routinely clear $10 million at auction, which is nothing to sneeze at, but the two LM-Specification cars could each be worth north of $15 million. In other words, you don’t have enough kidneys.
