I bought a used 2016 90D from Tesla in December - similar issues being weighed up.
AP1 vs 2; free supercharging, saving on a used vs new, and eventual resale price. Got a fantastic deal - fully loaded 6 seater for ~80K
Couple of things
- Tesla's used basically means they made sure the car turns on. My car had so many more scratches and issues than pictures they showed, I couldn't see car until I came to pick it up and then only choice was walk away or purchase as is.
I ended up spending $3K fixing up scratches and scrapes not pictured
The leather interior was way more worn than shown. And I know this is minor, but they hadn't even vacuumed the inside.
Probably the worst delivery of any car I have ever had - so things started on a sour note
The car had not been serviced in 2 years, so a LOT of things to fix - wind noise from windows was atrocious, shudder on acceleration etc.
Took it into Tesla Service, and warranty covered EVERYTHING - eg replaced entire window unit and glass. Granted, for first month, car in and out shop for about 4 weeks out of the first 6 weeks.
But liked the car, the free supercharging is pretty awesome.
My plan is to drive this car and see how it holds up till the warranty runs out, by then I imagine the EV market would have sorted itself out and I would have more options. In the mean time I get free supercharging for life and the warranty covers me for any issues that will prob arise
But here are the caveats the warranty does not cover :
BUT battery degradation is real!
I'm currently having aback and forth with Tesla about my battery, I currently can drive about 90 miles and go through 60% of my battery, so that's a total 100% of around 70 KW. That's more than the expected 3-5% per year drop that they throw around.
Actually not too evil for a long trip as free supercharging and breaks are ok; but terrible if you have to run around town/state for work/leisure on a given day where stopping for a 20-30 minute charge up in a supercharging station is not as convenient.
In all honesty, with winter weather, the car is more of a 120-130 mile car, than anything close to 2100, let alone the 250
Other issue that I never factored in; blind spot visibility is pretty cruddy in the MX. When i test drove the newer version, the better AP2+ made up for it; AP1 doesn't have that, Cars vanish in front of you when aligned with your font bumper and re-appear only way behind. The blind spot sensor is terrible.
Though I have just countered it by having the rear view always on but not the most elegant solution.
Whenever I got a loaner MX, it just felt much more solid and tight - I think build quality has improved a LOT. Your driving experience in a current day MX is not the same as what you will be getting in a 2016
Personally, I also love new shiny toys - so stings a little that all the new cool updates are off limits to me. And I don't mean the FSD, I don't think level 4-5 is coming anytime soon, and what AP1 has is good enough for me for now.
When this recent price drop came up, I ran the numbers, and I think I may have gone for a newer 2018 (though I would be hard pressed to get a 75)
Financially, prob better off with the 2016 (free supercharging, and someone else took the depreciation hit) but when you're spending north of 80-90K you expect some level of quality that a 2106 is less likely to give you. There is value to happiness and peace of mind
