2015 Peace, mercy, and blessings of God be upon you. I am offering for sale a 2015 GMC Sierra Z71, fully loaded with the highest specifications. It has front and rear sensors, collision warning, lane departure warning. The color is silver. The chassis is in excellent condition, body is factory condition with some minor, almost unnoticeable dents. The chassis The transmission has been overhauled, some parts replaced: transmission torque converter and transmission clutches. This is a known issue with the Sierra. The transmission fluid has been changed, and it is now in good condition, with no complaints. The engine is in excellent condition, has not been opened. However, it currently has a slight oil leak from the front engine seal that needs replacement, causing the leak. I haven't changed it yet; the cost is around 600 SAR. There is also a slight smoke that appears intermittently but disappears. Car mileage: 406,000 km The car, ماشاءالله (Masha'Allah - God has willed it), is solid in terms of suspension and undercarriage, with no issues regarding control arms, tie rods, CV joints, or CV joint boots. ماشاءالله (Masha'Allah), it's in great shape. Additions below: Installed an intercooler transmission cooler, 40,000 BTU, for approximately 1000 SAR. Installed Bilstein shocks for 3000 SAR. Installed a bed liner for 500 SAR. Installed performance spark plugs and performance spark plug wires, a complete set, and tuned them. Installed a bed light switch. Installed an anti-slip switch. Installed an Emirati muffler with a pleasant and enjoyable sound. Replaced the complete valve stem seals. Replaced rear brake pads and rotors. Programmed the fans. Disabled the DOD system. Performed an engine tune-up and cleaned the throttle body. Replaced the water pump. Replaced the transmission seal. Replaced the starter. And I replaced some other parts, but I don't remember them. The car has cost me around 10,000 SAR without the rims and tires that are currently on it. (Selling with the original factory rims, not the ones in the picture). Please do not lowball the car. If you don't know its market price, check the market. If it doesn't fetch its worth, it will remain with me.
