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).
Add the all-wheel drive to a Model S along with possible options, and the price rises to $138,000, according to the Tesla (TSLA) site. The most fully loaded version of the Model X will cost $143,750, according to the screen grabs posted on Tesla Motor Club. The six-figure price didn't seem to shock Tesla customers. I must say I am quite surprised at the price (as in, lower than I expected), said one post.
