NEVER BUY THIS YEAR

This is my 6th Gr Marquis/Cr. Vic. Loved the car. Currently have 2 of them. Lighting control modules - I'm on my 4th :D Ford definately has a problem with these, just had one rebuilt 2 weeks ago (on a replacement one that was guaranteed). NOW, I HAVE ALSO HAD A sudden accelleration problem, happened 2x before, both times "wet pavement" traction control was engaged, on. This time dry pavement, at high speed, and when shifting to neutral, engine was revving like it was going to shoot a piston through the roof. Finally shut car off and STOOD on brake (was doing about 60 when shut off). Called husband, happened to him once, only on mine. HIs 2003 (we have 2) never did it. Car now parked, Was going to take to ford to repair. I think I'm just replacing. This was my favorite car over 25 years. Not anymore. Safety is Job one, right? oh, I guess not, huh Ford.

Top pick for used car reliability & OK on MPG too!

Bulletproof engine and drivetrain, quiet comfy and upscale, cheap to buy used now and probably driven by a senor. Go for an 2003 or newer, simpler GS model, run 5-20 synth oil and replace lighting module for headlight weakness. Car is 4000lbs-basically a F150 engine, tranny and frame with car body. 25 mpg at 70+.

Most Comfortable Car

This is the third car in this class that I have owned so I knew what I was buying. The car is excellent condition, both inside and out. It is a replacement for one we lost so it is everything we expected and more. It could not have been cared for better.

All positive, except defective rear axles this yr.

In 2013 got this 2003 car from mother-in-law (little old lady). Car had only 24K miles, and now has 35K Have only one complaint and that is the fact that the rear wheel axles/bearings started to fail soon after. My research found that Mercury and Ford installed defective (soft) axles in many of this year's production. This repair costs about $750 for bearings, seals and axles (that's a quality non-dealer shop price). Listen for a "wha wha wha" noise that changes with wheel speed. Best heard with windows up and no A/C or radio on.

Big Mercury fan

My family, our businesses and I have owned over 100 Mercurys over the years. I recently purchased a beautiful 2003 Grand Marquis LS with only 78,000 miles on it. This is my fifth in this series. Three were wagons. I have really been happy with all of them for reliability, comfort and value. Very sad to see Ford drop the Mercury line. Very similar to Lincolns, with better price points. My son also recently bought a 2000 Grand Marquis LS. It is also holding up well. We also had a Crown Vic in the past. The Mercurys are more comfortable.

Reliabilty was this car's first name!

Ford made this most desirable of police and older drivers. Comfort on long trips, big big trunk space and room for a family of 5 . Why they stopped this American Dream is sheer stupidity.

Best driving cars around for the money

I've owned Lincolns,Fords and Mercurys my entire life. When looking for a family vehicle, the Mercury Grand Marquis, has everything a family needs. Seats up to 6 passengers comfortably (depending on a 3 passenger front seat or bucket seats). Mercury's drivability is the same as a Lincoln, smooth !!! Riding with the same drivetrain that powers our law enforcement vehicles ( Ford Crown Victoria). The powerful 4.6 liter engine is also economical on gas. For a full-sized family/luxury vehicle we're usually getting around 23 mpg on the highway. Also the 4.6 motors very dependable with regularly scheduled maintenance. No doubt about it it's a big car on the outside with an even bigger ride on the inside. Be comfortable in this one !!!
