1:47Buying a used Model 3: Highland or the original, and why HW3 vs HW4 matters
A used Model 3 can be a great deal, but the generation matters more than you might think. Here is how the original and the Highland differ, and how to check the self-driving hardware.
The Model 3 is one of the most common used electric cars in Europe and the US. But there are two very different generations: the original (2017–2023) and the updated 'Highland' version that arrived in late 2023. Here is how to choose.
How to tell them apart
- Highland: slimmer headlights, a smoother front without fog lights, C-shaped taillights, ambient lighting inside and a small screen for rear passengers.
- Original: rounder front with fog light openings, wood or textile dashboard strip, no rear screen.
What Highland improves
- A noticeably quieter cabin thanks to acoustic glass.
- A more comfortable ride.
- Ventilated front seats on most versions.
- Hardware 4 for Autopilot and FSD.
One thing to try on a test drive: many Highland cars have no turn-signal stalk; you indicate with buttons on the steering wheel. Some people get used to it in a day, others never like it.
Why HW3 vs HW4 matters
The original Model 3 from roughly 2019 to 2023 has Hardware 3 (some very early cars have the even older HW2.5). The Highland has Hardware 4 (also called AI4). The difference is growing: HW3 cars get a reduced 'Lite' version of FSD, and Tesla has said HW3 will not get unsupervised FSD or future major versions. Tesla has also said there will be no simple retrofit from HW3 to HW4. If self-driving features matter to you, this is a key reason to choose a Highland.
How to check
In the car, go to Settings, then Software, then Additional Vehicle Information. Next to 'Autopilot computer' you will see the hardware version. Without access, use the rule of thumb: original Model 3 means HW3, Highland means HW4.
What to check on any used Model 3
- Battery: ask for a battery health report; a modest loss of range over the years is normal.
- FSD: check whether FSD was bought on the car and whether it stays with the car after the sale.
- Tires and suspension: the Model 3 is heavy and quick, so tires wear faster than on a comparable petrol car.
- Warranty: the battery and drive unit have a separate, longer warranty than the rest of the car; check what is left.
The verdict
An original Model 3 is the best value if you mainly want an efficient, quick electric car. A Highland costs more but is quieter, more comfortable and future-proof for self-driving software.
