THE GUIDE LIBRARY

356 guides to checking a vehicle properly

Everything on this site, in one place: how the VIN itself works, what title brands mean, the quirks of each manufacturer, the vehicles that are not cars at all, and what genuinely differs in each state. Every guide cites official sources and says plainly what a check can and cannot tell you.

The two data hubs

VIN essentials

The mechanics of the number itself — reading it, finding it, and what it can never tell you.

Titles and brands

The permanent marks on a title, and what each one costs at resale.

Report services compared

The paid history services, and when each is worth the money.

Where we stand on money, data and access — and how to act on a charge from another site.

Brand VIN decoders

Make-specific decoding — WMI codes, option stickers, and the traps unique to each marque.

A guide explains the check. This runs one.

Seventeen characters is the whole ask. Nothing else is required and nothing is charged.

Beyond cars

Bikes, boats, trailers, RVs, trucks and equipment — where the numbering itself changes.

State by state

What genuinely differs where you buy — titles, inspections, taxes and regional risks.

License plates by state

Plate rules genuinely differ — who keeps the plate at sale, what a lookup can reach, and what plates quietly tell a buyer.
