Chevrolet 2007 with double

Chevrolet 2007, I want it and the engine and transmission are good, never been down (the double is disconnected) Air conditioning is icy, God willing Mileage 543 Agency engine, clean, but carbon appears due to oxygen sensors, oil pressure, and some sensor issues; I have inspected it, but whoever inspects it can find faults in any workshop (needs floor work) Today's auction price is 13 thousand, asking up to 15 0543283359
