Ford Grand Marquis 2005 Automatic Gasoline mileage: 285 KM Ford Grand Marquis, engine is guaranteed, gearbox is guaranteed, changed about a year ago, and thank God there are no problems. It needs a little work. The car needs valve seals and needs maintenance from underneath, and thank God it doesn't complain of anything. For sale for offers, and we won't disagree with a serious buyer. The car is fully repainted, and I don't know if it has major accidents or not from the previous owner, but I only had a front-end collision and changed the bumper only.
