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.

  I like the appearance and enhanced steering compared to my 1996 Grand Marquis. Only disappointment is noisey trim chirping on back doors on gravel road when car is cold.

  2003 GS Grand Marque - 2003 Mercury Grand Marquis
  By bdemedio - December 19 - 5:53 pm

  Superb vehicle. A Lincoln Town car for half price. Incredible power. 17 city is an underestimate- I get 20. I get 30 on the highway even with lights (rte 13 in Delmarva). No problems at all to date. Still smells new. 24 bucks a year upkeep and much lower than average insurance. The toyota avalon is JUNK compared to this. Some of them are already rusting. Ill play chicken with any of you avalon drivers anyday- you wont live and Ill walk away without a scratch. Anyone with children owes it to them to have this great machine because of its safety, durability, power, and mileage. Why do you think its the preferred car for cops and cabbies? Its the best car made in the world for the price.

  04 grand marquis - 2003 Mercury Grand Marquis
  By roger cozart - December 19 - 1:13 am

  Just purchased this car and love it. Traded in 04 Cadillac Deville with many problems. Mercury is a superior car. Handling is great and the car is really responsive and fun to drive. I hated the wallowing clumsy Cadillac. Lots of compliments on the appearance.

  great in every category, room, comfort and great road mileage (over 425 miles per tank full) but a bit poor in local driving.

  Classic luxury with sport performance - 2003 Mercury Grand Marquis
  By JSheehan - July 30 - 12:16 pm

  I have owned my Merc for a couple of months now it is my second Grand Marquis. Ive got the state trooper package so it handles amazingly (the air ride which is standard isnt bad either) The 4.6 puts out close to 300 for hp and torque (modest estimate) at its power band its probably well over that. You can red line it forever without over heating it. Super easy to install a super charger and HP chip which puts it over 500 HP and torque. Very nice interior/exterior. Avg 25MPG stock I get an AVG of 32 with the supercharger in it. Handling is comparable to large Lexus and Mercedes.

  Requiem For the Last True American Car - 2003 Mercury Grand Marquis
  By ftupka - July 2 - 8:34 pm

  Grand is the Mercury Grand Marquis middle name; this car is apologetically the last true American car on the road. While other vehicles rely on technology and styling that fades, the Marquis uses its heft and V8 engine to isolate you from the rest of the world. The quiet and smooth engine in my car has been trouble free even after 12 years. The transmission makes the most of the 224hp with the aid of Mercurys Precisontrac limited slip rear axle. Combine this with the last full frame in a sedan and the soft leather bench seats and you have a car that can easily carry five people (six when necessary) anywhere in solid comfort. Dont waste your time reading "enthusiast" reviews, just buy it!

  Grand Marquis is SAFE ! - 2003 Mercury Grand Marquis
  By saftey1st - April 19 - 2:00 am

  The Grand Marquis has kept my family safe, comfortable, and the reliability for this tried and true vehicle is incredible. A great purchase for those that buy their car with sound logic versus getting on the fad band-SUV-wagon.

  I really like the feel of the steering in the new Mercury. Much quicker. Also like the adjustable pedals since I am very short.Very pleased overall.

  Honest real world opinion - 2003 Mercury Grand Marquis
  By Thom - December 27 - 8:03 pm

  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.
