Elon Musk is worth $908 billion, and this weekend he asked world-class engineers to come join Tesla. Tesla once tried to cancel the sale of one car to the man who named the company. Martin Eberhard had already paid for Founders Series car number 2, and he had to sue to get it. Eberhard started Tesla with Marc Tarpenning in 2003 and was its first CEO. Musk wrote the biggest check of the first round, became chairman and later blamed Eberhard for the Roadster's delays and overruns. "I had paid full price in advance for this car. And they tried to rescind that deal," he says. Before he got it, a Tesla test driver drove it into the back of a truck. The car became part of his 2009 lawsuit against Musk. Founders Series cars were meant to carry a plaque signed by Eberhard and Tarpenning. By delivery he had been pushed out, and the plaque Tesla sent later had other people's signatures, not theirs. His license plate now reads FOUNDER. His daily Roadster came off a used lot in Los Angeles with about 175 miles on it. The previous owner, he says, was Justine Musk, who won it in the divorce and never drove it. Nobody had to sue for that one.
