Ford Grand Marquis 2010 Used Automatic Gasoline mileage: 400 KM or more Ford for sale, mileage around 400. Its engine and transmission are good. Leather electric seats for driver and passenger. AC is great, doesn't overheat. I've had it for a little over a year, I travel south and back with it, and it's been great, I haven't had any issues. Dealers, don't bother me. I put it in the showrooms two months ago, it reached 20.
