Great used car value with

by on
Vehicle: 2006 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Seats 6 (not on long trips however) and averages 23 mpg. Great trunk space. Reliability is one of the best and even beats a lot of Japanese luxury cars as noted by consumer reports and JD Power surveys. Highway cruising is the way it should be. Beats SUV and most crossovers for mileage and mine has traction control for winter driving ( I don't really need 4 wheel drive on paved roads). I bought it used very cheap because no one wants a v8 right now. Great choice for the used car buyer! Everyone thinks it's a geezer car (I'm only 42 and perfect for my family). Radio isn't powerful enough (maybe made for geezers). Pronounced wind noise and steering vibration.

Vehicle: 2006 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

we have just returned from a long trip of over 1800 miles and our new marquis performed excellently. A great ride, with good gas mileage.

Smooth ride

Vehicle: 2006 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

The auto handles well and gets good milage on the open road. It is stylish. If I had to find one fault I would say it could use better soundproofing. There is high road noise from cabin.

Disappointed in new mercury

by on
Vehicle: 2006 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

I bought a new Mercury Grand Marquis Premium LS about 2 weeks ago. I had it up to Interstate speed earlier this week and discovered that the wind and tire noise are horrible. It is so loud that it drowns out the radio. I took it back to the dealer who claims to have test drove it along with another new Mercury. He claimed the other new car noise was as loud or louder than my car. His conclusion was that the noise was a design flaw and there was nothing he could do. I have a hard time believing Mercury would manufacture a vehicle with this much driving noise, but apparently they did. I cannot and will not recommend this vehicle to anyone.

What's New for 2006

For 2006, the Grand Marquis LS gains 16-spoke, 16-inch alloy wheels, as well as an overhead console with compass and universal garage door opener. All models get a new grille, front fascia, headlamps and rear trunk applique.


One of the last surviving full-size, rear-drive American sedans from an earlier era, the Mercury Grand Marquis is an aged car. But under that familiar skin are some modern touches. A full-perimeter frame uses strong, lightweight hydroformed steel sections for the front rails to improve frontal and offset crash performance. Along with a stiffer frame, the Grand Marquis received a number of suspension upgrades in 2003, all of which contribute to the car's smooth, controlled ride and handling characteristics.

Other modern features include a variable ratio rack and pinion steering system with variable power assist and a dual-rate brake booster that automatically supplies full braking power in a panic stop. On the inside, the seats are comfortable, and there's room for up to six people. The 2006 Mercury Grand Marquis is mechanically identical to the Crown Victoria and similar to the Town Car. Decades-old technology allows Mercury to keep the prices low, and the Mercury car is a favorite among people who need space and don't want a minivan or SUV. Shoppers looking for a modern driving experience, however, might want to check out the Avalon, which is just as roomy and comfortable, and infinitely more refined.

Body Styles, Trim Levels, and Options

The full-size Mercury Grand Marquis comes as a four-door sedan in two levels of trim -- GS and LS. Each trim is further broken down into base and Convenience lines for the GS, and Premium and Ultimate for the LS. Base GS models include all the family sedan basics, like air conditioning; a CD player; a power driver seat; keyless entry; power windows, mirrors and locks; cruise control; a tilt steering wheel; and 16-inch wheels. The GS Convenience adds traction control and power-adjustable pedals. The LS Premium adds alloy wheels, a power front-passenger seat, automatic climate control and an auto-dimming rearview mirror. The LS Ultimate includes a wood and leather steering wheel with audio and climate controls. Options on both LS models include leather upholstery, a moonroof, seat heaters, a CD changer and a handling package, which offers a bump in power as well as firmer suspension tuning for better handling.

Powertrains and Performance

Only one engine and transmission are offered on the Mercury Grand Marquis. Standard models use a 224-horsepower, 4.6-liter V8 and a four-speed automatic to put power to the rear wheels. Opt for the handling package on either LS model and the same engine is upgraded to produce 239 hp, along with a boost in torque to 287 lb-ft (from 272). Fuel economy is respectable for a large V8-powered sedan -- expect about 17 mpg in the city and up to 25 mpg on the highway.


The Grand Marquis scored well in National Highway Traffic Safety Administration crash tests; it earned a perfect five stars in frontal-impact testing and four stars in side-impact testing. The big sedan also earned the top rating of "Good" in frontal-offset crash testing conducted by the IIHS. Four-wheel antilock disc brakes are standard on every Grand Marquis, and traction control is standard on all cars except the base GS. Seat-mounted side airbags for front occupants are optional, but side curtain airbags and stability control are not available.

Interior Design and Special Features

A roomy cabin is one of the biggest selling points for the Mercury Grand Marquis, and adults will find plentiful head-, shoulder, hip- and legroom. Bench seating allows this big sedan to accommodate up to six people. A cavernous trunk of 20.6 cubic feet will swallow any luggage they might have with them. Controls and instrumentation are simple in design, though not particularly stylish, and some of the materials are low in quality.

Driving Impressions

Want a chrome-encrusted, rear-drive V8-powered American sedan without the premium charged for a Lincoln or the trendy Chrysler 300C? The 2006 Mercury Grand Marquis fits the bill perfectly. The standard V8 provides plenty of acceleration in just about any situation, and the car's smooth, forgiving ride spares occupants from harsh impacts over bumps. The large size of this Mercury car can make it unwieldy in tight spots, but it's relatively responsive steering helps drivers keep it on track.
