When the clock strikes midnight, it won’t only signal the end of 2018. It will also mark the end of the full $7,500 tax credit for Tesla buyers.

As we reported earlier this year, Tesla sold its 200,000th electric vehicle in the United States and that means the federal tax credit for Tesla buyers will be going away. The full $7,500 rebate will expire at midnight and be reduced to $3,750 on January 1st. It will then drop to $1,875 on July 1st, before eventually being phased out completely.

In order to ensure as many people as possible can claim the full tax credit, a number of Tesla dealerships will remain open until midnight. Tesla CEO Elon Musk tweeted out of a list of dealers participating in the last-minute sales blitz and there are more than 40 in states such as California, Florida, Georgia, New York and Washington.

Last minute buyers won’t necessarily have the best selection, but Electrek’s sources have suggested there are over 3,000 Model 3s in inventory. Buyers can also opt for the Model S and Model X as well as an assortment of fleet vehicles.

While customers can’t be choosey, the $3,750 saving is significant and would effectively lower the cost of the Autopilot option on Model S to just $1,250. Of course, at this point, customers will likely have to settle for what’s available.

Customers who have already ordered a vehicle and haven’t gotten it delivered yet, aren’t necessarily out of luck. Musk has previously said “If Tesla committed delivery & customer made good faith efforts to receive before year end, Tesla will cover the tax credit difference.”
