GMC Sierra 2012 Used For sale GMC Sierra 2012 Mileage 365,000. The car is solid, its engine and gearbox are good and have no problems. It has not been used for heavy-duty work, nor has it been exposed to harsh conditions. Recently replaced the seals and exhaust system. There are scattered paint touch-ups, and paintwork due to the installation of the roof rails. Replaced new shock absorbers, new control arms, and the engine filter. The rest of its issues are fine. It needs some touches and tidying up, and I haven't had the time due to my commitments. It has two seals. Whoever buys it, I will give him headers + Y-pipe + K&N filter. Latest offer is 32,000. Only serious buyers should contact me via WhatsApp.
