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).
Teslaâs share price is now close to $175, after having fallen more than 40 percent from its high last July of $286. Morgan Stanley analyst Adam Jonas said he cut the target because sales prospects of the new Model X SUV, currently reaching its first customers, and the mass market little Model 3 have been scaled back.
