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.

Read the truth sheet

See what that exact car was built with, from the Full Self-Driving computer to battery type, heat pump, screen, and the known issues for that build window, each one marked Confirmed, Very likely, or Check the car.

Decide at the car

Know what's real, what to check in person, and what's normal for its battery, before you hand over money.

Point it at the VIN, anywhere it is.

Scan the barcode on the door, or just aim the camera at a printed VIN: a listing on your screen, a window sticker, a photo someone sent you. And when you're standing at the car with no signal, it still works, fully offline.

It tells you how sure it is.

Every verdict comes from documented Tesla rollout windows and reads Confirmed, Very likely, or Check the car. When the data can't settle it, Valette says so and tells you what to look for.

Written like someone's telling you, not spec'ing you.

Faster screen, not a version number. Which Autopilot computer is in the car, not a feature-package name. Plus the known issues for that exact build, and what to actually check when you're standing there.

The battery question, with real numbers.

Worried about the battery? The data is calmer than the headlines. Most Teslas keep 87-93% of their range past 100,000 miles. Valette shows what's normal for a car's battery type and age, the number that's a real warning sign, and how to get its battery properly checked before you buy.
