2015 Chevrolet Tahoe LTZ

Owners selling privately get 13% to 20% 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 LTZ: 353 of the 355 cars we’ve seen with this VIN pattern are. Median of 40 final asking prices of this trim & year (listings that ended), adjusted to 161k mi ($15,667 nationally), where it is (Texas −2.1%).
