The Tesla Roadster was the car that started it all for the company. And although the Tesla Roadster is primitive by today’s standards, it was the standard bearer for what a production electric car should be. There were points in time when Tesla was almost out of money bringing the Roadster to the market (via Car Buzz).
The earliest Tesla Roadster models were plagued with bugs and issues, but it was enough to get the company ahead. The Roadster was a success for Tesla and it was one of the most futuristic vehicles on the road.
