This Year's Model Updates:

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.

Pros:
  • Plenty of interior room, comfortable ride, excellent crash-test ratings.
Cons:
  • Large size makes it difficult to park and maneuver, grandpa-car image.

  • Honest real world opinion - 2003 Mercury Grand Marquis
    By -

    My driving and ownership experience. Hmm. Well all said and done, second too none. The MGM is by far the best car I have ever owned, inside and out. Ive given this car the highest ratings all around including fuel economy. I find though my research most larger cars as well as mini-vans or other family sized vehicles average around 20-25 mpg. I average about 25 mpg (26.7) to be precise with my Grand Marquis. Now factor the size and weight and power of the car and compare that on a scale to ANY small car or large car. You will find the MGM is the green or most fuel efficient car on the road. Outside of fuel economy, I rate the reliability five stars. MGM has a proven record and still holds it.

    Very nice car with plenty of room and great ride. Engine slightly noise but with plenty of power, but price to pay with less than desirable mileage.

    rented a marquis in 99 in seatlle and fell in love - bought a new 2000 in nov 2001. current is 03man, these vehicles are the best thing on the road - maybe a LTcar might do better??? - i am disabled and carry a scooter lift w/auto air lifts, all told about 300 lbs on a 2 inch tow - both gave me so much comfort and ease of being able to get around n the pleasure of driving - i feel like its power is more then enough - i drive at 70-80 on trips n have hit 90 enroute to las vegas - this car just cruises! its just a smooth - mpg arent the best, but most cars dont carry what i do - even with the lift, scooter, baggage etc, ride is smooth n performance is great - i love my marquis..

    after 2 prior Marquis which did not offer service, I really was hesitant to buy this 2003...the updates it afforded allowed me to chance it once again...Gas mileage seems less than the prior 95 which was repurchased by Ford due to many things wrong, and 96 LS with air suspension, that lasted 69000 and blew 2 cylinder heads...2003s rear end whine needs to be explored by the dealer..handling is far superior to prior models and wind noise is still annoying..has only 4000 miles at present.

    Grand Marquis LSE - Its more fun than a regular LS. With dual exhaust, floor shift & 3.27 gears, its a pleasure to drive and gets excellent gas mileage - 24 plus on the road. Ive owned it 8½ months now, have put over 24000 miles on it, and cant find any fault with it. I absolutely recommend this car.

  • SLOW SERVICE FROM DEALER - 2003 Mercury Grand Marquis
    By -

    I TRADED IN A 2001 GRAND MARQUIS ON A 2003. THE FIRST DAY I NOTICED THE TRANSMISSION SURGED IN REVERSE. THE DEALER REBUILD THE TRANSMISSION TWICE & IT WAS STILL BAD. FINALLY THEY PUT IN A NEW FACTORY TRANSMISSION & IT WAS OK. THIS TOOK 37 DAYS SO THE LEMON LAW KICKED IN. NOW I AM WAITING FOR A REPLACEMENT CAR. I LOVE THE CAR BUT THE SERVICE WAS BAD.

    Fine road car- easy to drive on long trips. Lots of room and protection for the driver and front seat passenger.

  • The last great American sedan - 2003 Mercury Grand Marquis
    By -

    The Grand Marquis isnt a perfect car, but its close. Driving is effortless. The base V8 provides more than enough power to get you into trouble. The car gently glides over bumps and potholes instead of jarring the passengers like most cars. Handling is surprisingly sharp for such a large car. It has enough room to seat five adults comfortably and an extra seat belt if you have to take six. I have the LS Limited, which is almost as nice as a Town Car for a lot less. Because Ford rarely changes them and the old cop Crown Vics flood the used market, there are plenty of deals available. These cars last forever, so even a used one will probably last longer that most new cars.

  • Ultimate Grand Marquis - 2003 Mercury Grand Marquis
    By -

    This is an excellent automobile for the consumer looking for confort at an affordable price. The gas mileage is acceptable as it averages about 20 mpg on regular fuel and around 28 mpg on the highway. It has plenty of power for passing and driving in mountains. I personally prefer the rear wheel drive over frontwheel drive as it handles much better. The rear air suspension really smooths the ride. It is so quiet that the driver hears hardly any wind or road noise. The only thing I would change are the inside door handles. They should be chromed metal and not the hard plastic, after all this is the ultimate Grand Marquis. .
