GMC Sierra 1998 Manual Gasoline mileage: 44 KM Sierra 1998 manual transmission original. It has driven 44,000 miles, and I don't know if the mileage is real or not. I got it when it was parked in a prince's palace since 2015 because of the license plate on it. I transferred the license plate, and the car is ready for transfer, and it has a nice license plate. I don't know anything about the car at all, and I got it without inspection. However, I installed 5 tires with balloons for about 4,000. I don't have a set price, and the price is based on offers.
