Tesla CEO Elon Musk tweeted this week that the company will stop selling the lowest-price versions of Tesla Models S and X.

The 75 kilowatt hour versions of those models.

The starting price for the S is $76,000 and $82,000 for the X.

The last day to order them is Sunday.

After that, the S and X models will only be available with a 100 kilowatt hour battery.

That will put the starting price at $94,000 for the S and $97,000 for the X.

The Model 3 sedan starts at $44,000. It is Tesla's first mass-market vehicle.
