Yeah that is our thought. We bought a used 2018 TM3 LR AWD from Tesla in 2022, with 33k miles on it. It now has 105,000 miles on it. We're going to drive the wheels off this thing because we love it so much. Came with FSD (transferred to our 2024) and Acceleration Boost - (3.6-3.8 second 0-60 is amazing). Yes, it was a little expensive, and we still owe more on it than it's worth but ... with the driving we do, we're saving so much $. Was nice using the carpool lanes up till last month too. lol.
My 2024 M3 LR AWD - loved our 2018 so much, had to get one for me. I owe just about what it's worth on it (thanks to federal tax credit and some $ down). But I intend to drive this thing till the wheels fall off. Was hoping it would get acceleration boost but a 4 second 0-60 is more than I ever need.
The savings we're getting doing 0 maintenance - 0 oil changes - 0 waiting in costco gas lines (not to mention 0 gas especially here in NorCal) - ... it adds up like crazy very quickly. (My wife got free work charging for several years).
The only 2 year maintenance I did on our 2018 was ... fill the window washer fluid reservoir. That was eye opening and mind boggling. We have 70k tires on it now and it is going to go another 100k easily.
