Elon Musk now sells used cars. The billionaire's electric car company, Tesla Motors, quietly launched a pre-owned vehicle program at the end of April — a new scheme that offers older versions of its Model S sedan for lower prices than new models. The used cars still come with Tesla maintenance and reliability checks, and like other high-end car makers, Musk's company gives a 4-year or 50,000-mile warranty on pre-owned vehicles.

A Tesla spokesperson told The Wall Street Journal that the used cars would be stored at a Tesla location, allowing customers to collect their car directly, or have it delivered to their home. For now, limited supplies of the used Model S electric cars mean that the new scheme is currently only available in 11 US cities, with supplies coming from display models or owners who traded their older sedans in for new all-wheel-drive models under Tesla's trade-in schemes. But the company can expect an influx of older vehicles soon, as owners who bought their first-generation Model S on a three-year lease in 2013 return the car to the manufacturer.
