GMC Yukon 2012 model, first owner, quick sale

I am offering a GMC Yukon, brand new agency condition, with some dents shown in the pictures. The car needs a gearbox, and the engine had a manufacturer defect which has been fixed by replacing the seals. The seats are in local condition, I covered them the day I bought the car, and the floor has been covered since I purchased it until now. The driver and passenger doors need their internal handles fixed, while the two rear doors are intact and have no issues. The registration is up to date, first owner from the agency. The mileage is 400,000. The price is 23,000, negotiable
