Vehicle: 2003 Mercury Grand Marquis LS Ultimate 4dr Sedan (4.6L 8cyl 4A)

Purchased new and garaged in Florida. Driven mostly around town. Averages 20 MPG. Bought to carry six people and does so comfortably. Most dependable car I have ever owned. Has extra chrome plus gold package and looks like new car. I also own Infinity M37X, Toyota Sienna and BMW Z4. I particularly enjoy driving the Mercury which elicits smiles from my family.

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Ford F150 engine, drive train and frame with car body! Very reliable, cheap to maintain, upscale in out and 20mpg on regular! 2003+ are the best years-big changes in suspension & steering! Dirt cheap to buy used now and they stopped making them in 2011! May have baby boomer demand coming-sleeper used car?? They make driving relaxed and there is no substitute for a V8, long wheelbase and 4000 lbs of quiet ,mass on a long freeway trip!

What's New for 2003

The 2003 Grand Mark receives a number of updates. The most important ones are hidden. A new full-perimeter frame uses strong, lightweight hydroformed steel sections for the front rails to improve frontal and offset crash performance. Redesigned frame crossmembers and new optional side impact airbags improve side impact crash performance. Additionally, the new frame -- combined with a redesigned independent front suspension and new monotube shock absorbers at all four wheels -- contributes to a smoother, more controlled ride and improved handling. Other changes include a new variable ratio rack-and-pinion steering system with variable power assist and a new dual-rate brake booster that automatically supplies full braking power in a panic stop. On the inside, the seats have been changed to improve comfort and appearance, the cupholders are new, a three-point seatbelt has been added for the center rear passenger and the door trim has been redesigned for a cleaner appearance and better ergonomics. To spot a 2003 Marquis, look for the brighter headlights and subtle new styling applied to the front and rear of the vehicle.
