Jay Leno
To my knowledge, there isn’t a celebrity alive that can compete with Jay Leno when it comes to his car collection. Where Jerry Seinfeld may have focused on one particular brand, Leno has an extremely diverse collection that could include anything from a steam powered car that might produce 2hp to what he calls the Blastolene Special that has an engine from an M47 Patton tank under the hood that produces more than 1600hp.
