Tesla co-founder and CEO Elon Musk is the undisputed king of electric cars. In large part because of his early investment in electric vehicles, Forbes claims Musk is the world's richest man, worth a staggering $255.1 billion, which is more than enough to acquire the rarest and most expensive cars known to humanity.

Musk’s current collection ranges from vintage cars like a 1920 Ford Model T and a 1967 Jaguar E-Type Roadster to a first-gen Tesla Roadster, a Model S, and a Cybertruck. His first car was a first-generation BMW E21 320i, later followed by a Hamann BMW M5 E60 sedan, but among his favorites is a 2012 Porsche 911 Turbo.

To celebrate his $1.5 billion sale of PayPal to eBay, Musk bought a McLaren F1, one of the rarest and most expensive vintage sports vehicles on Earth, with only 106 units (only 64 of which were road-legal variants) built from 1992 to 1998. Unfortunately, Musk totaled his McLaren when he hit a barrier and went airborne, but being Musk, he later sold the car for a profit.

The most expensive car in Musk's current collection is a Lotus Esprit that he paid $920,000 for at auction. Moreover, it’s no ordinary Esprit — it's the submarine car from the 1977 James Bond hit "The Spy Who Loved Me." Musk was disappointed to learn the car doesn’t actually transform, but he plans to upgrade it to a Tesla electric powertrain and make it amphibious in real-time.
