Well Tesla was unique because in January 2023 they cut MSRP of 3/Y by 20% overnight.
Have you thought about selling privately? That's what I've done with the last 3 Teslas we sold about to do it with my Cybertruck. KeySavvy makes it super easy if you have a loan on the car still. They handle all the paperwork, verify payment, get the title from the bank after payoff etc.
Thats exactly what happened to us, we bought our m3p used in dec of 2022 and a month later tesla slashed prices, we could have got a new one 3 years newer for less than we paid for the used one. we put a large down payment, had a very low interest loan and still couldnt keep up with the depreciation. in the 3 years we owned it, the NADA dropped by around $30k, we bought a 4runner around the same time, put about the same amount of miles on it, kept it 4 years and sold it for $3500 less than we paid. gotta love toyota.
