2015 Used mileage: 277 KM 4WD Sierra 2015, second owner. Mileage 277 thousand. Airbags are guaranteed. Engine: The head was removed only, and the block was removed to change the seal. All glass is original GM glass. The spare tire has never been used. Body has scattered paintwork. Additions: Trucool transmission cooler 40,000 BTU + an Oxide thermostat and its elbow [I replaced them out of caution, as it had no issues before or after]. The car is solid and well-maintained, and has not been tampered with, neither its wiring nor its programming. Everything is original from the factory (factory programming has not been removed).
