How it works
01

Get the VIN in

Scan the barcode on the driver's doorjamb, or type the VIN from the windshield or the listing. No VIN? Check by model and year instead.

02

Read the truth sheet

See what that exact car was built with — Full Self-Driving computer, battery type, heat pump, screen, and the known issues for that build window — each with an honest confidence level.

03

Shop with confidence

Know what's real, what to check at the car, and what's normal for its battery. Save candidates and compare them before you decide.

Built for the lot, not the couch.

Fully offline — it works standing at a car with one bar of signal. Open the driver's door, scan the barcode, read the truth. Faster than typing 17 characters into a website.

Verified, not vibes.

Every verdict comes from documented Tesla rollout windows with an honest confidence level — Confirmed, Very likely, or Check the car. When the data can't settle it, Vinnie says so and tells you what to look for.

Speaks first-time buyer.

Plain language, not forum jargon: faster screen, not "MCU3"; what the Full Self-Driving computer means for you, not a version number. Plus the known issues for that exact build window — and what to check at the car.

The battery question, answered honestly.

Worried about EV batteries? The data is calmer than the headlines: most Teslas hold 87–93% of their range past 100,000 miles. Vinnie shows what's normal for that car's battery type and age, the one real red flag to watch for, and exactly how to get this car's battery verified — because a VIN can't measure a battery, and we won't pretend it can.
