This is exactly what I'm thinking.This makes the Tesla unappealing, I'm seriously contemplating just buying a second hand ICE at the current rates and cutting my losses with waiting this long.
I budgeted this car at the lower $6xk price (I can't remember what it was in Jan/Feb). By the time I had convinced myself it was a good idea, the price had gone up. Interest rate remained low so I didn't mind as much.
Now, any other year in the last 5+ the wait wouldn't have been an issue at all, however this year every month rates have risen. The fact I'm paying more money for the car + higher and higher interest rates push this to a cost I'm not comfortable with.
If I get an invoice before the 4th on January I'll keep my order, as I'm locked in for 4.99%, however if I have to re-apply with what ever rate January has for us I'll likely cancel.
