Purchase price: Tesla Model S and Model X. Base prices for the 2017 Tesla Model S sedan range from $68,000 to $134,500, depending on package; the 2017 Model X crossover ranges from $88,800 to $138,800. Further upgrades are available (more on that below).
Most buyers opt for the larger battery despite its $10,000 price, Tesla says, for the added range and security. Prices range from $70,000 for the base Model S 70 to around $135,000 for an absolutely top-of-the-line P90D with all the options. The Model S is thus an expensive car that competes with mid-size and full-size luxury sedans, though Tesla has ambitious plans for a $35,000 electric car it says it will unveil during 2016. The Tesla Model S was a handsome and sleek design when it launched in 2012, and it remains so today.
