Window Sticker & Build Sheet Guides

How to read an original window sticker, what a GM RPO build sheet or a Stellantis factory build sheet tells you, where to find your VIN, and how to check the equipment a used vehicle left the factory with. For Chevrolet, Buick, Cadillac and GMC, the VIN lookup returns the original window sticker when one is on file and otherwise the RPO build sheet; for Chrysler, Jeep, Dodge, Ram, Fiat and Alfa Romeo it returns the factory build sheet, when available.
