2023 GMC Sierra 1500 AT4

Owners selling privately get 7% to 10% less than dealers ask for the same trim, year and mileage. The low end is how the big pricing guides value a private sale (what buyers pay dealers, less a private-party discount); the high end is what private sellers’ asking prices and private-party sales show. A trade-in usually fetches less still.
