The short version
Buying used Model Y is about three things: battery health and warranty, hardware generation, and accident/history verification. Everything else is negotiable cosmetics.
Before you buy
- Check the battery: use the car’s energy screen and range estimate; a large deviation from rated range suggests degradation or a history of deep cycling.
- Confirm warranty transfer: battery/drive unit warranty (8 years / 120k miles on Long Range) transfers with private sales in most cases — verify with Tesla.
- Hardware generation matters: HW3 vs HW4 affects future FSD capability claims. Check the vehicle config.
- Service history: ask for service records; repeat visits for the same issue are a red flag.
- Check for salvage/flood history via VIN history services — battery damage is not always visible.
Model Y generations
2020-2024 (Gen 1) vs 2025+ (Gen 2/Juniper): interior, suspension, and noise improvements in Gen 2. Decide whether the differences matter for your budget.
