Ford Expedition 2011

I am offering my Ford Expedition 2011 model, no accidents, only right-hand steering modification. The car's mileage is approximately 450,000 and negotiable. I suspect but am not sure there is an issue with the oil pump and brake booster. The car's engines are in good condition. Most of the maintenance was done at Quick Lane when the car's mileage was only 70,000; recently after 400,000 I stopped agency maintenance. The car is solid, only the previously mentioned notes apply.
