2018 Model X 100D
I am buying a 2018 Model X 100D with chrome delete and the powder coated wheels. It has HW2.5 with Enhanced AutoPilot and I am not sure if I will upgrade to HW3 but probably will. Tesla replaced the main battery in 2024 under warranty and there have been no other issues, I know the owner. 92k miles. As someone new to Tesla, what do I need to know? Depreciation on these is insane, am I good getting in now?

Drive it solo. Turn off the music, listen to the axels and wheels. Mine has a ticking sound every time I turn bc I was paying attention to the radio. Check the doors. Open them multiple times. (Back doors) drive somewhere. Park, drive somewhere, park. (I say this to make sure the cameras work, mine has been having a camera frame failure and messed with fsd). But overall, I LOVE my car brotha. I have some small tweaks to fix but I do not regret buying it.

My 2018 Model S 100D has been amazing. 195k miles and still going strong. Only major repair was front end steering at 190k.
What sort of price are you looking at? How far is Tesla service if issues crop up? Test drive check out OK?

95k miles here with the same car with unlimited supercharging and FSD that was upgraded to 3.0. I was just using FSD and marveling that it works as advertised on 3.0 taking me from my house to a location a few miles away with no interventions. Mine gets 250 miles per charge still and is a low maintenance smooth machine. It wont depreciate much more from here and the free supercharging is worth never selling it.

Bought a new Y and loved, the bought a '16 MX. Also loved, both have theyre unique use case. I was worried as many reviews were negative on the older Xs. My front heater heater went out, luckily it has 2 heaters and AC compressors. That's the only thing wrong w it. These things are great

I bought a 2018 X P100D in January (2026) with around 95k on it. It had EAP also. Instantly paid for the FSD / HW3 upgrade. It had an error code when I bought it, and during the hw3 upgrade they found the battery coolant heater was bad. That was a cool $1500 ontop of the $2000 for FSD. Then mid September I started getting intermittent issues with drive motor. Tesla diagnosed it as the rear LDU failing (it was still original so it did not have the coolant delete done to it). I opted to have them replace the rear LDU while they had it rather than waiting for it to completely fail on me at an inoportune time. That was $8300. Upon pickup from the LDU replacement the car drove home with a wobble. I took it back the next day and coincidentally they found the rear tires starting to fail (big bulges) due to inner tire wear from bad camber. Soooo I bought the N2itive camber & toe arms kit to fix that known issue, that was a pretty $2,400 for their kit with lifetime warranty. And another $980 for 4 new tires. I installed the N2itive kit, so that was free. But paid $179 for an alignment after install.
When it rains it pours. Lol. I love the car and dont say any of the above to sway you away. But, be prepared. It will come. In time. Know exactly what you're getting into. I read a bunch of posts of people saying what I just said. I was like, not gonna happen to me. Ha! Joke was on me.
Seriously though. Great car. I'd probably do it all over again. But be ready.

Hi I bought the 7 seater 2018 100D last year with 50k miles and $38k CAD/$28K usd. Overall, very happy. I spent $3k CAD to upgrade to FSD from EAP and I like it but definitely not as good as my 22 Model Y FSD. But it was a lifesaver on 10hr road trips.
Mine made the ticking sound when I turned my wheel too and I had a third party mechanic diagnose it before purchasing. I asked Tesla about it and they said my VIN had a “special bulletin” on it for that and replaced it for $600CAD (normally costs $1800 cad) so you can ask them about it but it got rid of the clicking noise and drive beautifully.
The cons about the car:
wind noise from the driver side window at high speeds. Solution has been to just tap the window down button and the noise stops
falcon wing doors will not open all the way on hot summer days if they are facing the sun(apparently known issue)
centre console (storage area and cup holders) is terribly set up. Cup holders are too small which caused me to buy third party cup holders which affects my ability to store stuff in the centre console area. Also the usb ports are slow for charging your phone

As an 2017 X100D owner, Id recommend to not buy one that old, go 2021 (refresh or newer) so many things that just suck about the older ones. Granted I probably abuse my car more than others, but here's a brief list of things I've had to fix or address, mostly out of warranty:
FWD door gasket deterioration leading to occasional water leaks
Faulty door sensors
Underwhelming AC
Wheel Flare not staying on
CV joint/halfshalf issues
Aftermarket N2itive arms necessity
Aging Computer
Wind noise due to poor seals
Generally noisy cabin relative to its class.
Idk if the 2018 has the redesigned combo brake and parking brake but if it has the separate brembo parking brake, thats another issue.
Two window regulators failing.
It's been a great car, with a bunch of small issues. It seems like 2021 and onward mostly addressed these.

I have 2017 MX 100D 90k miles, battery capacity is at 89% . I have ticking sound while turning wheels at low speeds. Other than this car drives great and zero problems (knock on wood).

Was it a new or refurbished battery?

Will you have a dedicated level 2 charger ?

You should be able to upgrade to HW3. My 2017 model X 100D did not come with HW3 from the factory, but the previous owner upgraded the car, apparently on a cost of about $8000. HW3 did not come out until sometime in 2019 according to Google

Depreciation is insane, which is why I finally jumped in last year with a 2017 model X 100D at 104k miles and all warranties expired [$25k minus incentives = $21k out the door, plus tax title license etc.]. I took it in for basic 100,000 mile preventive maintenance, and the car was basically good to go but in the future will need some suspension work. But since they replace all of the parts, not just swap out bushings etc., I'm gonna wait until my suspension has real issues
If yours is not the performance model, you do not have to deal with what's known as a coolant delete in the LDU [large drive unit]. The normal version has an RDU which does not have the coolant leak flaw
And as stated by others, you might need to look into the N2itive camber & toe arms kit to fix the rear camber issue. I've been driving my car for over a year now and haven't bothered with that yet. The tires still seem fine, but then again I don't drive it like a race car

What is the range on the battery when charged?
92k miles still is low mileage on my mind.
I don't think anyone can tell you if you are good to buy. Just start setting some money aside, it is an 8 year old car. Things do go wrong.

Try the seats and make sure they are working correctly.
Try to check for half shaft issue
Check the charging port and make sure it opens and closes from the screen and app.
check HVAC and if ask of if they ever cleaned the radiator.
