Most celebrities have a garage full of fancy cars, but not like the guys on this list. These celebs have motor oil in their blood, so they can't help but to buy, drive, and customize their rides!
Probably the most famous gearhead of them all is Jay Leno. This late night talk show comedian has an almost unhealthy passion for automotives. He owns around 200 different vehicles (half cars and half motorcycles), and his collection is filled with rare gems and one-of-a-kind models. Leno's massive garage not only contains rare cars, such as a 1994 McLaren F1, but also equipment for repairing and maintaining them.
