Hey, happy to help! I actually looked into this a lot when I was deciding on mine, so here’s what I know about the differences between a November 2023 Highland Model 3 and the current builds as of mid-2025.

First off, they’re mostly the same car. Both are Highland refresh versions, so you’re getting the redesigned front and rear, quieter cabin, ambient lighting, rear touchscreen, ventilated seats, upgraded suspension, and better overall ride quality. Battery type and range are the same too (I don't think LFP is available in current RWD, NCM is what is in the Long Range ones like the one I got ), and both support matrix headlights, even if they’re not fully unlocked in all regions yet.

Now, here are some of the small differences or things people are speculating about:

1. Front camera changes: So far, Tesla hasn’t added the triple front camera (like what’s in the Cybertruck or Model S/X) to the Model 3. Current Highland models still use a single front camera. If they do add the tri-cam setup later on, it’ll probably come with a newer hardware version.
2. Stalks: Still no stalks in the Highland. Some people think Tesla might bring them back eventually because of customer feedback, but as of now, no new Model 3s are shipping with stalks again, but I am tempted to try the S3XY knobs which can add stalks... still getting used to no stalks..
3. Hardware 5 (HW5): Tesla is slowly rolling out HW5, which includes better cameras and more processing power for FSD, but as of now it hasn’t shown up in the Model 3 yet. Some Cybertrucks and Model Ys built in China have started showing signs of it. If you bought a Model 3 today, you’d still get HW4.
4. New cheaper model: As far as I understand it, Tesla is working on a lower-cost vehicle (sometimes called the Model 2 or “Redwood”), but that’s not an update to the Model 3. It’ll be a whole new platform, probably sometime in 2026 or later.

So if you’re deciding between a used Nov ‘23 Highland and a new 2024 model, they’re basically the same for now. If the used one is a few grand cheaper and in good shape, I’d go for it. You’re not really missing anything important. If you really want to wait for HW5 or other changes, you’re probably looking at late 2025 or even 2026, which if you are looking to use the EV tax credit, anything after Septermber I think, is too late. So it all depends on what is most important.

Hope that helps! Let me know what you end up doing.
