Tesla is hoping to clear out some of its Model S and Model X inventory, which is great news if you’ve been holding out. Tesla recently notified current Tesla owners that it is discounting some Model S and Model X models up to $30,000.

2017 Tesla Model S, Tesla Model S Review

The keyword here is “some” since the big discount is only available on the top spec Model S P100D and Model X P100D. With the discount applied you can lease the Model S P100D for $1,500 a month and the Model X P100D for $1,600 a month with 10,000 miles a year. If you’d prefer to finance either model, you can get an interest rate as low as .99%.

While this may sound great there are a few caveats. The discount can only be applied to current dealer stock and it is “off the original configuration price,” which means that the vehicle in the current stock may be more expensive than if you were to order a similar vehicle with the same options. The vehicles may also not be entirely new, since they could have several hundred to thousands of miles, like a dealer demo model or service loaners.

Either way, if you want to get discount on either a Model S or Model X you have until the end of September. If you’re interested you can find these discounted models check them out .
