Faceless used-Tesla helper
Don't buy the wrong computer.
Paste a year, model, trim, or VIN. See whether the car is likely Hardware 3 or Hardware 4, then score the ask against used 2024/2025 Performance bands and new Model 3 Performance at $54,990.
Hardware checker
Conservative calls. 2024+ Highland Model 3 = HW4. Pre-refresh 2017–2023 Model 3 = HW3. 2024 Model Y is called uncertain on purpose.
How it works
01
Year or VIN
NHTSA vPIC decodes Tesla VINs when it can. If the API fails, year and model still run.
02
Hardware call
Refresh rules, not wishful thinking. Uncertain stays uncertain — including 2024 Model Y.
03
Deal screen
HW3 is a dealbreaker for HW4/FSD-computer shoppers. HW4 M3P is scored vs used bands.
