2010 Automatic Gasoline mileage: 300 KM or more For sale: Grand Marquis 2010. The car's undercarriage has been completely redone. The body is like new. The car needs a tune-up and the ABS computer, I think, according to the workshops. The entire undercarriage was redone two months ago. Mileage is 480,000, its maintenance is regular. My price is 25,000 for whoever wants to finalize the deal. The car is ready and I'm still using it, and I just tuned it up.
