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.

  2 ton of fun! - 2003 Mercury Grand Marquis
  By drjjjj - December 9 - 6:54 pm

  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!

  a stiffer suspension would be nice.biggest gripe is the long hood and would like another 3-4 inches legroom for the back seat.

  Cruising in style! - 2003 Mercury Grand Marquis
  By BriGuy - July 15 - 4:20 pm

  What a wonderful car. Great power. Smooth ride. Consistently getting 23- 25 mpg in a V8! 103K now and idles like new. One repair in all that time, big one though: transmission. Manufacturer defect once repaired shifted better than ever. This is my most recommended car I have ever owned or reviewed by far!

  Someone in these reviews made a very good point. He said that cabbies and cops use these cars. I own a taxi cab business. Mercury Grand Marquis are simply reliable, fun to drive, powerful vehicles.

  Hard to be Objective - 2003 Mercury Grand Marquis
  By Waggly Toast - May 1 - 9:50 am

  Its hard to be objective when the car is perfect. Weve had it for a year and weve never had a single problem with the vehicle. We purchased it from my Grandmother and she never had a single issue either. We towed a 3K lb. trailer from AL to UT and it handled the trip with ease. No problems whatsoever. Gas mileage for the trip was around 15 mpg. I was amazed. The car rides smooth and is very quiet. Three car seats fit in the back with plenty of room and we can seat three adults up front. We have enjoyed owning such a reliable vehicle. We put about 15K miles/year on the vehicle. We would recommend it to everyone.

  Nice car but ride could be improved - 2003 Mercury Grand Marquis
  By Edward Briggs - February 28 - 10:00 am

  Air Conditioner worked great. 8 way power seat and back lumbar kept me from getting fatigued on I-95 Plenty of power from 4.6 liter V-8 allowed us to merge safely. Plenty of trunk space for our luggage. Smooth ride on Interstate but a little herky jerky on secondary roads. Plenty of cabin room for us to stretch out 4 speed auto tranny shifted great. I like the outside buttons on the drivers door, in case you lock your keys inside. Spare tire is steel full size rim, and you can use it when you rotate wheels. Remote control from key ring is convienient to lock and unlock trunk lid and doors. Headlights give ample candle power at night driving.

  Lots of car for the money! - 2003 Mercury Grand Marquis
  By Jay Taylor - February 4 - 10:00 am

  This is the 1st Mercury Ive bought in 33 years. The last one was a 1964 Park Lane and that was a powerful car. I am very pleased thus far after trading in my 1995 Park Ave. Though the ride on the Park Ave was a bit smoother,this Mercury is much more responsive and a lot more fun to drive. Gas milage overall about 22.5 MPG-Not bad for a 235 horse power V8-Its the LSE model-- very close to the Maurader-very sporty!

  Best Car Ever! - 2003 Mercury Grand Marquis
  By Pat Malarkey - January 10 - 10:00 am

  Who likes going to work? But I love driving to work in my Grand Marquis. This is my third Grand Marquis in 10 years and I am 100% satisfied. The car is fast, comfortable, and runs strong. I set the temperature and the car heats or cools the cabin automatically. I hope my next Grand Marquis is just as good! Rear wheel drive cars are great!
