Review of the 2003 Mercury Grand Marquis

  • Thousands of Floridians can't be wrong! A Lincoln Town Car at Honda Accord prices.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2003

    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.

2 ton of fun!

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

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!




Oldie but a goodie!!!!

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

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!




Still outstanding!

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

This is still one outstanding vehicle. I have owned a Buick, Chevrolet, Dodge, and several Pontiac's, 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? Grandpa's is so much smarter than you think, because he had this right!

Cruising in style!

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

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!




Classic luxury with sport performance

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

I have owned my Merc for a couple of months now it is my second Grand Marquis. I've got the state trooper package so it handles amazingly (the air ride which is standard isn't bad either) The 4.6 puts out close to 300 for hp and torque (modest estimate) at it's power band it's 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 put's 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.




Best bang for your buck

Vehicle: 2003 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Have owned this car for 3yrs bought it used with 39K has 75k miles now and it has just been super! No mechanical problems at all. Rides excellent handles excellent. Had it recently in snow and ice with no problems. I'm looking to purchase a newer Grand Marquis within the next year. Gas mileage is 27hwy and 19 city. City could be better but compared to the size and room its a bargain. SUV with same seating area get much less. I love the RWD it is so stable no hydro plaining on rainy roads. I hope Ford Motor doesn't quit making this excellent car!
