Here's the essence of the scheme: Hertz, urgently needing liquidity, has heavily written down its fleet of 30,000 Tesla vehicles and is selling them 100% on Carvana's platform. At the same time, it has used social media to create momentum, attracting a large number of Tesla/Musk fanatics, and then selling the Tesla cars at relatively high prices, earning much higher profits and profit margins than normal business operations.
