The report gave some additional information that CarFax did not show, and from that I was able to make a more informed decision on the purchase of a used Corvette that I was looking into.
What a GMC window sticker shows
The window sticker — formally called the Monroney label — was required on every new vehicle sold in the US under the Automobile Information Disclosure Act of 1958. Every GMC window sticker includes:
- Manufacturer's Suggested Retail Price (MSRP): the original sticker price including base price, options, and destination charge
- Standard equipment: every feature that came included with the base trim
- Factory-installed options: each option added at the factory, individually itemized with price
- Option packages: bundled features sold as named packages
- Fuel economy estimates: EPA city, highway, and combined MPG ratings
- Crash test ratings: NHTSA 5-star and IIHS ratings where applicable
- VIN and ordering information: the exact build configuration
For used GMC buyers, the window sticker confirms what the vehicle actually came with from the factory — distinguishing genuine factory options from later dealer or aftermarket additions.

Why used GMC buyers want the original window sticker
Three reasons the window sticker matters when you're buying a used GMC:
Confirming factory options vs aftermarket modifications. A seller can claim a feature is "factory" when it was actually installed after delivery. The window sticker is the definitive record of what came with the car when it left the factory. This matters for genuine sport packages, factory navigation systems, factory tow packages, premium audio systems, and other high-value options.
Verifying genuine performance variants. Some GMC cars exist in both performance and appearance-only versions. The window sticker reveals whether the car is the genuine performance variant or just trim-styled to look like one. GMC window stickers use the same RPO codes as Chevrolet. Denali trim packages are typically the most option-loaded GMC window stickers. GMC Sierra and Yukon Denali stickers are commonly requested.
Original MSRP for value calibration. Used-car pricing software (and your own negotiation logic) uses original MSRP as one data point. Knowing the actual original MSRP — not the estimated MSRP based on visible trim level — helps you negotiate from a more accurate baseline.
How to read a GMC VIN
GMC VINs typically begin with 1GT (light trucks) or 3GT (Mexico) — GM's shared VIN architecture with Chevrolet.
The 17-character VIN unlocks the window sticker record. The VIN is located on:
- The lower-left corner of the dashboard, visible through the windshield
- The driver's side door jamb sticker
- The vehicle title and registration documents
- The insurance card
- Some GMCs also display the VIN on the engine block, on the firewall, and on the certification label inside the driver's door
How to get a GMC window sticker
Step 1 — Enter the VIN. Type the full 17-character VIN above. The system identifies the GMC model year and configuration.
Step 2 — Review the Monroney content. The retrieved window sticker shows MSRP, options, packages, fuel economy, and crash ratings , the same content GMC originally printed on the window when the vehicle was new.
Step 3 , Save or print. Download the window sticker as a PDF for your records, listing, or negotiation. Used GMC listings with the original window sticker attached tend to sell faster and at higher prices than identical vehicles without it.
GMC popular models with notable window sticker content
These GMC models commonly have option-loaded window stickers worth retrieving:
Sierra 1500, Sierra HD, Yukon, Yukon XL, Acadia, Terrain, Hummer EV
For trucks and SUVs especially (where towing capacity, payload, drivetrain, and bed configuration all appear on the Monroney), the window sticker is often the cleanest single document confirming the vehicle's actual capability.
GMC's manufacturer portal
MyGMC (account required) is GMC's official source for window sticker retrieval. Some GMC portals require a registered owner account; others let you look up by VIN directly. The Zilocar window sticker lookup works without an account, returning the same Monroney content from aggregated sources.
