2017 GMC Sierra 1500 SLT

Owners selling privately get 8% to 12% 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.

Priced as SLT: 506 of the 526 cars we’ve seen with this VIN pattern are. Median of the 40 asking prices of this trim & year closest in mileage (128k km–190k km), each moved to 160k km ($25,058 across Canada), where it is (Nova Scotia −1.6%).
