Review of the 2008 Mercury Grand Marquis

  • The 2008 Mercury Grand Marquis is old, handles like the U.S.S. Nimitz and is outdone by a variety of equally large, safe and powerful competitors -- including Mercury's own Sable. Only those who yearn for 1970s-era land yachts need apply.

  • Safety
  • Pros

    Low price, spacious interior with six-passenger capacity, comfy ride, torque-rich V8, good crash test scores.

  • Cons

    Ancient design and underpinnings, sloppy ride and handling, outpaced by newer competitors in almost every way.

  • What's New for 2008

    The Mercury Grand Marquis sails into 2008 with only minor changes to the options list. A new rear air suspension is available, while last year's Handling Package that increased power and improved handling has been eliminated.

Really nice car

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Most driving is around town. A very comfortable city ride over railroad tracks and street bumps and the many turns made at intersections.

A reliable car

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Our 2008 Grand Marquis has been both a fun and reliable vehicle. Around town gas mileage is not a good as our 1997 Crown Victoria - Crown Vic was in the 16-17 mpg range, and the Grand Marquis is in the 14-15 range. While a major consumer magazine calls it an old and stodgy vehicle, it suits us just fine. We're very pleased with it.

Update after 3 yrs of

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

I am updating my review from 3 yrs ago. The car is running great, it is still extremely comfortable but the paint is peeling off everywhere; very disappointing. It has already been repaired under warranty once and I will have to take it back to the dealer again for the same reason. It's really sad; such a beautiful car with such lousy workmanship. I hate to admit: I was wrong praising it.

New engine after 3000 miles

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

I bought my Grand Marquis new it was an 08 left over. I took the car in for an oil change, and a slight knock. after a three day diagnosis, came to find out that the #5 cylinder went bad. Ford approved a new engine to be installed can not find out if in fact a new engine is being installed or if its going to be a rebuild! Tried to get dealer to let me trade into something else, but after owning car for 6 months they said it depreciated $ 8000, so getting new engine, let see what happens!

Another great marquis

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

This is my 5th Marquis. It's a 2004 purchased with 21,000 miles for a measly $14,500. Car needed some work to start, about 1,500 with some rear axle problems. I was surprised. After driving these things for 16 years its the largest repair bill ever. Well crafted, old style RWD, nice looking lots of room good handling a real highway car. You can't find a better machine without selling the farm. They rearly break down. Could be one of the best cars in the world for this price.

The way it should be

Vehicle: 2008 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)

Before I bought my MGM, I test drove the baseline models of Lexus, Infinity, Cadillac, Jaguar and tried to test drive the Mercedes C300. They all felt the same and very much looked the same. Have to look close before I can tell them appart. Because of my job, I drive into Mexico every day; I need comfortable; feeling the road is not really desirable and with all these cars you actually feel the road. Went to the Opera recently and the wow's my MGM got were not been given to the CTS' and the Mercedes. In my opinion there is nothing wrong with old as long as it works well and looks great. What happened to distinctive US designs? Why do critics push for oriental clones?

What's New for 2008

The Mercury Grand Marquis sails into 2008 with only minor changes to the options list. A new rear air suspension is available, while last year's Handling Package that increased power and improved handling has been eliminated.


When is a car retro without trying to be retro? When it's the 2008 Mercury Grand Marquis. Based on an automotive platform design that dates back about 30 years, the Marquis features rear-wheel drive, a live rear axle and body-on-frame construction -- the latter of which is a design attribute kept alive in modern cars solely by the Grand Marquis and its relatives.

This old-school approach to car design does have a few benefits, namely its robust simplicity and cheap maintenance costs (which, naturally, make it a favorite of the nation's livery and law enforcement communities). But there's a reason other full-size cars are no longer built like this big old Merc -- actually, there are quite a few reasons. More modern competitors offer just as much interior room, and they deliver it in a more stylish, functional package. And by virtue of their more sophisticated engineering, most offer a vastly superior driving experience.

For non-fleet buyers, the 2008 Grand Marquis' principal selling points are its ample size, rock-solid safety performance and relatively low price. Anyone in this country who has at some point ridden in the backseat of a Grand Marquis or Crown Victoria taxi (or perhaps a cop car) knows how large the interior and trunk are. Hip and shoulder room are particularly impressive thanks to the ultra-wide body.

But compare the Grand Marquis to Mercury's own full-size '08 Sable (formerly the Montego) for instance, and the advantages fade away. The Sable's trunk is a tad larger; its rear-seat head- and legroom are more generous; and its crash test scores are identical -- in fact, IIHS rated it as a top safety pick. Plus, the Sable's about the same price, has a similarly powerful but more fuel-efficient V6 engine and a higher-quality interior, drives substantially better and has a wider array of available features. Notice a pattern?

The 2008 Mercury Grand Marquis' longtime platform-mate, the Ford Crown Victoria, is now sold only to fleet buyers. That means regular folks who still want one of these automotive relics must stick with the Grand Marquis or the more expensive Lincoln Town Car. Although the Mercury has some limited appeal, we simply cannot recommend it when there are other full-size sedans that meet or vastly outdistance the Grand Marquis. In addition to the Sable and the nearly identical Ford Taurus, other large sedans like the Chrysler 300, Hyundai Azera and Toyota Avalon are much better choices.

Body Styles, Trim Levels, and Options

The 2008 Mercury Grand Marquis is a full-size sedan available in two trim levels -- GS and LS. Base GS models come with 16-inch steel wheels with faux chrome wheel covers, air-conditioning, a CD player, a front bench seat with power adjustments for the driver, cruise control, automatic headlamps, full power accessories and keypad entry. The Grand Marquis LS adds 16-inch alloy wheels, foglights, automatic climate control, leather upholstery, power seat adjustments for the front passenger, a leather-wrapped steering wheel, a rear-seat fold-down armrest, an auto-dimming rearview mirror, heated side mirrors and an overhead console with a compass and Homelink garage door opener.

On the options list for the LS, you'll find stand-alone items like a sunroof, heated front seats and an upgraded audio system with a CD changer. The Palm Beach Edition Package includes chrome wheels, chrome-trimmed mirrors, cashmere leather seats embroidered with "Palm Beach" logos and satin-finish metallic interior trim. A rear air suspension is optional on both GS and LS trim levels.

Powertrains and Performance

Only one engine and transmission are offered on the Grand Marquis: a 4.6-liter V8 coupled to a four-speed automatic that sends 224 horsepower and 275 pound-feet of torque to the rear wheels. Fuel economy is on par with other large V8-powered sedans, with 2008 EPA estimates at 15 mpg city/23 mpg highway. However, those competitors offer much more horsepower.


Antilock disc brakes are standard on every 2008 Mercury Grand Marquis, while traction control is optional on the GS and standard on the LS. Power-adjustable pedals and front seat-mounted side airbags are optional on the LS, but side curtain airbags and stability control are not available on any Grand Marquis.

Despite missing a few safety features, the Grand Marquis nevertheless has scored well in tests by the National Highway Traffic Safety Administration. It rates a perfect five stars in frontal-impact crash protection and, when equipped with side airbags, it earns five stars for front and rear side-impact safety as well. (Without the bags, it gets four stars.) The big Mercury sedan also earned the top rating of "Good" in frontal-offset crash testing conducted by the Insurance Institute for Highway Safety.

Interior Design and Special Features

The Grand Marquis has a wide, spacious interior that can seat up to six in a pinch. Nevertheless, the rear seat is matched or surpassed in roominess by newer, better-driving full-size sedans. Controls and instruments are simple and easy to decipher, but the overall design is dated. The trunk is quite large, with 20.6 cubic feet of space capable of swallowing copious amounts of luggage or several sets of golf clubs.

Driving Impressions

Like the interior, driving the 2008 Mercury Grand Marquis is none too different from piloting one from 15 years ago…or even 15 years before that. Due to the vehicle's size, pillow-like suspension and low-effort steering, it has all the road feel of a two-mast schooner. These may seem like positives to some folks, but quite simply, newer full-size sedans are easier to maneuver and better to drive, while still offering safe structures and comfortable rides. On the upside, the standard V8 provides plenty of acceleration for any situation, particularly on the highway where the Grand Marquis is best suited.
