New York (CNN Business) One of the biggest Tesla short sellers is feeling pretty good about his bet against the automaker.

Jim Chanos told CNN's Julia Chatterley on "First Move" Thursday that he thinks it's a mistake for Elon Musk's electric car company to make luxury versions of its Model 3, a car originally billed as an affordable mass market option.

Musk's company has been under intense pressure to meet production goals for its Model 3 and has focused on making a more expensive $60,000 version, and delayed the cheaper option. Chanos says there's only so much room in the luxury market -- about a million cars a year.

"I would remind you that that's the car that was supposed to be sold for $35,000." Chanos said.

So, Tesla ( TSLA ) may be pulling out all the stops to make projected sales numbers for the third quarter, but Chanos thinks that might be as good as it gets.
