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.

  2nd marquis LS limited - 2003 Mercury Grand Marquis
  By tbones - September 12 - 11:26 am

  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..

  One Fine Automobile - 2003 Mercury Grand Marquis
  By T.H. Wells - August 18 - 6:23 am

  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.

  Ultimate Grand Marquis - 2003 Mercury Grand Marquis
  By Mike Elliott - December 25 - 10:00 am

  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. .

  Very Satisfied Customer - 2003 Mercury Grand Marquis
  By tmarie - October 25 - 2:00 am

  I previously owned an Oldsmobile, Cutluss Supreme. I loved my little car and it gave me lots of miles, well over 100,000.00 however; it was time to retire her. In looking for a car, I had not considered a Grand Marquis until I, by chance drove one. The luxury, handling ability and extreme comfort sold me. I absolutely love my car. I feel very safe and the ride is so smooth. My father has always owned cadilacs, my car is every bit as smooth and comfortable a ride as his car. I cant say enough good things about this car that I by chance came to own.

  A Great Car - 2003 Mercury Grand Marquis
  By Harlan M - March 26 - 2:00 am

  I love the electronics on the car, it is equal to a much higher priced car. Auto temp control is great.

  2nd Time Around - 2003 Mercury Grand Marquis
  By Grand Marquis Fan - March 5 - 2:00 am

  We had a 1996 Grand Marquis that we just gave to our son so I shopped around for a replacement and found myself back at the Mercury dealer. I was quite pleased with my first one: a safe and reliable car which I can entrust to my teenage driver when Im willing to share. After 116,000 miles in 6 years, it only needed brakes, tires and minor adjustments. Love the 2003 as well and it has even more convenient features than the 96.

  My Third Grand Marquis - 2003 Mercury Grand Marquis
  By Dannydog - January 11 - 10:00 am

  This is my third Grand Marquis,Ive had a 1994, a 1999 and now a 2003. I am also a law enforcement officer and have driven the Ford Crown Victoria. They have all proven to be safe, reliable and a comfortable ride. Those cars I used during work took a real beating with going over curbs, hours of idling with the air conditioner or heater runnning and having mileage well into the 100,000s. They always continued to run well and comfortable not to mention the safety factor. (I also was an ambulance technician for over six years.)This is why starting in my early forties I started to buy the Grand Marquis and intend to continue to.

  underappreciated car - 2003 Mercury Grand Marquis
  By Thorn11acr - October 22 - 8:23 am

  This is my first "panther platform" car. Im 60 and have had hundreds of car and pickups. This is by far the most bang for the buck. I switched to Mobile 1 synthetic oil in 5-30w, added dual exhausts with an "X" pipe in the stock placement. Would you believe 28 mpg with the A/C on. I would imagine I can hit 30+ on the highway on cruise at 70mph. A simply great car, it rivals my Mercedes in comfort and handling....and replacement parts are dirt cheap. Even the Russians use this vehicle as their police cars. Rear wheel drive, proven drive train, and for 2003 you get a lot of improvements...Simple, strong, reliable.

  Still Outstanding! - 2003 Mercury Grand Marquis
  By Uncle Philly - September 17 - 4:10 pm

  This is still one outstanding vehicle. I have owned a Buick, Chevrolet, Dodge, and several Pontiacs, and none of them compare to this vehicle. I have had zero problems with my Mercury. I could never say that with the other makes that I have owned. This car seats six in comfort, very smooth ride, huge trunk, excellent acceleration, very low maintenance, and gas mileage at 20 mpg city, and 26 mpg hwy. If you have a heavy foot you will be closer to 18 city/24 Hwy. They call this a Grandpa mobile....Ha! Why ride in a cramped, horrible riding, dinky mobile, when you can ride in comfort at a low price? Grandpas is so much smarter than you think, because he had this right!
