Good question. I’ve been through something similar with a Crossfire purchase a few years back. The “original” dealer sticker (the big printed one on the window when the car is new) and the Monroney copy usually give you a decent overview — window sticker https://carfast.express/en/window_sticker , major packages, basic trims — but often they skip optional extras, small packages or custom factory-installed items. When I first got the paperwork for my car, I compared it against what I saw physically: several items listed on the window sticker weren’t there, and a few parts on the car weren’t listed on the sticker.
