Put one on order, immediately. Think of it as buying a $250 lottery ticket, pricey, but with great odds. When it is ready for delivery you will have a much better idea about whether buying it is a good idea or not. Almost certainly there will still be enough demand for the car that you can accept it and sell it for a profit, or sell your place in line. Traditionally, car's are depreciating assets and poor investments. Tesla's currently and probably for the near future, are appreciating assets and with a locked in price during high inflation, you can't hardly get hurt.
In the meantime, start putting that $1,300 monthly payment away. Set up an investment account if you don't have one and start buying Tesla shares. It really doesn't matter what they cost, they are going to increase so much. If you get a VIN assigned in 6 months, you will have saved up $1,300 x 6 = $7,800 and learned that you can handle doing without $1,300 per month that you have been spending previously, (and whether you really want to or not). In 6 months your stock will be worth so much that you will likely reconsider investing in a car and want to continue buying Tesla stock.
By the time the VIN is assigned if you have been unable to save $1,300 per month, then you will know that you can't handle the car payment and must not try it. You will likely still be able to sell the car for a profit and get a few hundred or maybe even thousands for your $250 investment. If something drastic happens between now and then so you can't claim and sell the car or find a buyer, then you will lose the $250, but it will have been a grand adventure and you will have learned lots. Good Luck.
