What’s the real difference between an Original Window Sticker, a Monroney copy, and a Carfast VIN report?
Can someone explain in simple terms how the original Window Sticker, the Monroney sheet, and a Carfast lookup differ? I keep seeing all three mentioned when checking used cars, but the info doesn’t always match. Which one is considered the “correct” version, and why are there multiple sources in the first place? I’m honestly confused at this point.

I’ve compared these across a few cars, and each one serves a different purpose. The Monroney copy is basically a sales-friendly summary MSRP, major packages, and sometimes small items like floor mats or accessories. The original Window Sticker is the most accurate, but almost impossible to get once the car changes owners. When I ran VIN checks through monroney label https://carfast.express/en/window_sticker , it pulled the full factory build data: option codes, tech packages, premium audio, driver-assist systems — all the stuff that actually matters when verifying what the car left the plant with. They’re simply pulling from different databases, which is why the details vary.
