Seems like some folks are assuming if they can delay until the end of the year they will be able to get Spring/ Summer 2021, delivery in January, and collect the incentives.
You are ignoring a very real possibility here. Tesla may well just unilaterally cancel any of these older orders on December 31st. That would mean you have to place a new order and take delivery whenever they are next available (likely late summer-fall for the MY LR). The message Kaisoku posted above seems to suggest that is not only possible, but likely.
Something interesting is that I have both a Model 3 and a Model Y reservation.
I made the Model 3 Reservation on 4/8/2016 (RN107138---) just when the Model 3 reservation started (and people waited on line outside of the store) !!!
I never been requested to activate my Model 3 reservation that I still have.
I think many people have also Roadsters and Cybertrucks reservations too.
I made the Model Y Reservation on 4/28/2019 (RN109336---) just when the Model Y reservation started.
I received at least three requests to activate my Model Y reservation.
From My previous experience, I bought my current Model 3 in 2018, just before the end of the $7,500 Tax rebate.
Then, for 6 month the Tax rebate was then $3,750 and ended in June 2019.
However, the Model 3 at that time was constantly changing to attract customers.
Well, in July 2019, even without any Tax discount, the Model 3 equivalent to the one I bought with Tax discount, was cheaper.
I wonder in January, if there is a Tax rebate, if the Model Y after Tax rebate, will be lower, about the same, or higer than the current price?
It’s very much in your best interest to figure out with some certainty what happens on January 1st before you continue down this path.
I am not used to change car every so often, mostly because of the 10.25 % sales tax in California.
When buying a new car, you pay again the taxes on based on the full price, not just the trade-in.
Also, because of the Covid situation I have a very low mileage, so I have no real justification for getting a new car.
However, if someone is interested getting my Model Y reservation, and known how to proceede, I am fine with it.
