Parts & Accessories Spare parts 2014 mileage: 243 KM Peace, mercy, and blessings of God be upon you. I am offering for sale a used Sierra 2014 SLE. The car has 243,000 miles, third owner. I have maintained regular oil changes. Engine oil is changed every 3000 miles. The car has two hits on the chassis, and the engine has been disassembled. There is a sound that suggests it's from the steering rack. The car is generally good for use. The car is active. I just changed the spark plugs, all the oils, and the tires are new. It has been offered to me for 45,000 and 49,000. The sale is easy and close.
