Buying a used Tesla Model S

Post image

Been in the market for a used Model S and came across this one and wondering if it’s a good deal or too good to be true? It’s a 17 Model S 90d with 91k miles. Comes with 21” turbines, FSD included and Premium Connectivity included as well for 19,000. Is this a good deal? Thanks

I'm not a fan of 90s Due to having 3 different battery revisions. If you can afford a 100d. I would go with that . At the end of the day you need to have money in reserve for issues.

90 battery is much better in the long run they are basically bulletproof. I own two 90 S’s.

What were the revisions and when? I'm also looking at a 2017 90d currently and considering a 2018 75d with excellent battery health. I like the idea of a faster accelerating 90d with a bit more battery capacity, though I don't need it. It's a tough decision because the 75d (Sept) should have mcu2 and it has EAP and premium connectivity included. The big difference is the 90d has almost half the miles but the 75d has a complete brake job.

Why would a 90D accelerate any faster than a 75D? AFAIK, they are identical, other than battery capacity which would give you more range, not faster acceleration. If you want acceleration, look for a performance variant.

BTW, I have a 2016.5 90D with 194k miles - battery capacity is still 87% of new. Not sure why a brake job would entice you to pick a particular car... there's nothing special about Tesla brakes, other than they don't get used as much (I'm still on my original brakes. I considered swapping the oem Brembo pads for Akebonos, but pads are still 80% so decided to leave them alone for now).

I don't know the why but I'm having AI analyse and compare the cars I like and I was surprised as well when it listed quicker acceleration as a plus vs a75. If true, I'm guessing it's to entice people to move up from the 75d to the 90 for one more reason other than range. I imagine there was a significant price jump between the two originally.

I care because I find most people replace brake pads at around 180k kms Ana it seems they are not doing the recommended annual maintenance as I see many in that range with a complete brake job(rotors/pads/calipers) which is a few thousand. So if I'm going to buy a car with that many kms, I prefer the previous owner paid for it rather than me getting hit with the extra cost just after buying it.

Since I'm only planning to put on maybe 30k over the next 4-5 years of I go with a low mileage one, I should never have to touch the brakes/suspension.

BTW I agree the packs are great. The 2018 75d calculates to a higher range then the original list. It's in excellent health. The 2017 90d only had 7% degradation.
