GMC Sierra 2014 mileage: 300 KM or more GMC Sierra 2014 modified to 2018. It has a slight jerk in the transmission, but the rest of the engine is in excellent condition. The body has paint on the lower part of the driver's door only. Airbags are in excellent condition. Mileage is 300,000 km. I am looking for a trade for a Camry from 2018 and above. The current offer is 55.
