Overview & Reviews

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.

• Plenty of interior room, comfortable ride, excellent crash-test ratings.

• Large size makes it difficult to park and maneuver, grandpa-car image.

  My Mercury - 2003 Mercury Grand Marquis
  By Roy Creekmur - May 17 - 10:00 am

  I like it because its a real "American Style" car. It has rear wheel drive and a basic suspension design thats been developed and proven for 70 years. Its what I wanted, and built, like, I like a car built (body on frame).

  2003 Mercury Grand Marquis LS Limited - 2003 Mercury Grand Marquis
  By Matt - May 14 - 6:00 am

  Beautiful car, comfortable, powerful, reliable. This is my second Grand Marquis (94). The best used vehicle you can buy period. Good choice for a new vehicle too, but they depreciate fast. Bought it with 30,000 now at 72,000. Only problem: A/C only blows out of defrost.

  WOW!! - 2003 Mercury Grand Marquis
  By JR1949 - February 20 - 10:00 am

  I went from an 85 Crown Vickie to this 2003 Grand Marquis LS Convenience. What a difference! The 03 handles like a car 1000 pounds lighter. The non-air suspension offered in this model offers just enough "road-feel" to make it fun to drive. Considering its size, frontal area & mass, the fuel economy isnt bad!(22 MPG avg-mixed city/hiway, ~26 pure hiway) My heart sunk when I realized I had left the windows open one evening during a moderate rain, yet the leather wiped off perfectly. So far, its about the BEST car overall, Ive ever owned; I consider it a mini- Lincoln! Ford-this ones a keeper!

  My 5th GR MARQUIS - 2003 Mercury Grand Marquis
  By dadof9 - January 14 - 2:00 am

  My only real complaints have to do with the road/air noise on the highways. To the point where the radio/ CD are not enjoyable. Disturbing enough to make me think of another vehicle.

  Oldie but a goodie!!!! - 2003 Mercury Grand Marquis
  By Brian - December 27 - 7:23 pm

  134,000 miles and counting! I have not lost a drop of oil or have a spot of rust! And they said American cars are no good. Ha! I average 23 mpg 80/20 highway/city. Still as smooth as the day I bought it and by the way for those who are curious about repair costs...it literally is the cheapest parts of any car made in the last 10 yrs. So its a low cost commuter too. The wheels will have to fall off before I let it go!

  03 Grand Marquis Ultimate Edition - 2003 Mercury Grand Marquis
  By hjones4841 - August 27 - 9:03 pm

  This is my fifth Grand Marquis and wont be my last. Reliability is excellent, with one exception - at just over 36,000 miles the right rear wheel bearing started whining. I found out that this was a problem for 03 Crown Vics and Grand Marquis built prior to Jan 03, which mine was. Both rear axle bearings and the spindles were replaced. The car was out of warranty, but since I was a regular customer of the dealer, I got a pro- rated partial warranty payment. Fuel economy tops out at about 25 highway at cruising speed of 75 or so. Best ever fuel economy was on my 99 Grand Marquis on a cool morining, driving 70 mph - 29 MPG! Seats are comfortable,even with my wifes and my back trouble.

  I may have bought my last Mercury - 2003 Mercury Grand Marquis
  By Richard - June 25 - 1:23 am

  I love the big body on frame, V8 RWD Mercurys. I believe they are going to drop the Grand Marque. They are down to one model, with few options. You just cant get all the options offered an there other models. If you could I may be in the market for one. I love my Marauder and dont plan on getting rid of it I would like a second car like the Grand Marque. I guess I will have to go for something else. So where do I go? Cadillac, BMW (overpriced).

  LSE03 Is So-So - 2003 Mercury Grand Marquis
  By Ray66 - April 26 - 2:00 am

  Leased this LSE right before Mercury discontinued the option. Prior leased car was a Crown Vic LS. The Crown Vic got better gas mileage, was quieter and rode much smoother. The LSE supposedly has a slightly more powerfull engine but I see little difference. The LSE has more bells and whistles and a more usable interior but I miss the Crown Vic
