Secondhand cars are like snowflakes: Every one is different.
With their dents, stains, smells and leaks, used cars might seem more difficult to sell online. Yet startups Beepi, Carvana, Shift and Vroom, which sell only used cars, are growing far more quickly than new-car specialists.
According to CrunchBase, a website that tracks startup funding, Beepi, Carvana, Shift and Vroom have raised $530 million in debt and equity financing since 2013. Most of them don't disclose data on transactions and revenues, but it's safe to say these companies sell thousands of cars a month.
Roadster, which has raised $4 million, sells about 100 vehicles a month.
"The used-car companies are about 18 to 24 months ahead of us in terms of personnel and funding," Roadster CEO Andy Moss said. "We see them as kindred spirits at different phases of the life cycle."
