Tesla introduced its Resale Value Guarantee in 2013, when buying an upscale electric car was a riskier prospect. What if your Model S was worth less than a tried-and-true German sedan? However, the market has clearly grown up since then... and Tesla is changing accordingly. The automaker tells The Verge that it has discontinued the program for any new car bought in the US after July 1st. The move will reduce interest rates "as low as possible" and sweeten leases and loans, a spokesperson says. You're still protected if you bought a car under the guarantee, but any relative latecomers will just have to trust that the used EV market will work in their favor.
