2005 Mercury Grand Marquis Review

Spacious cabin and comfortable ride at an affordable price.

Reviewed by Automotive on


The 2005 Mercury Grand Marquis is available in five trim levels: GS, GS Convenience, LS Premium, LSE, and LS Ultimate. The original Mercury Grand Marquis was introduced in 1975, but the most recent generation of this long-running model began in 1998. Over the years, the Marquis received a variety of updates. The biggest changes were in 2003, when the Grand Marquis received an all-new chassis with a redesigned front suspension and rack-and-pinion steering. Despite its two-ton curb weight, the Grand Marquis is reasonably quick off the line thanks to a 4.6-liter, V-8 engine. On the road, the Mercury Grand Marquis delivers a soft, forgiving ride, although the handling lacks precision. The vehicle’s greatest strengths are its value for the price and a roomy interior for five or six passengers, plus plenty of cargo room in the trunk. Along with the Ford Crown Victoria, the Mercury Grand Marquis is one of the last traditional body-on-frame cars being sold in the U.S.

What's New

The Grand Marquis receives minor changes for 2005, including a new instrument panel applique, a revised steering wheel design, and new wheel choices. The LSE model is new and includes a duel exhaust, sporty axle ratio, unique wheels, and leather bucket seats with a floor console and shifter.


The 2003 overhaul of the Mercury Grand Marquis included styling changes to the grille, front fascia, headlamps, integrated cornering lamps, and tail lamp lenses. The front rails of the full-perimeter frame are comprised of lightweight, hydro-formed steel sections. An optional handling package includes a rear stabilizer bar, rear air suspension, and aluminum wheels. Built on a 114.6-inch wheelbase, the 2005 Grand Marquis measures 211.9 inches long overall and stands 58.4 inches tall. Standard features on the GS and GS Convenience models include a chrome grille; 16-inch steel wheels; cornering lights; auto-delay-off, dusk sensing headlamps; and power door locks, mirrors, and windows. The LS upgrades to alloy wheels and adds heated mirrors. The sporty LSE and the LS Ultimate add remote keyless entry.


The 2005 Grand Marquis can hold up to six occupants in front and rear bench seats, except for the LSE. The large trunk holds 20.6 cubic feet of cargo, and a trunk organizer is available as an option. Standard GS equipment includes a CD stereo, a height-adjustable, eight-way power driver's seat with power adjustable lumbar support, a front passenger seat with manual adjustable lumbar support, simulated wood trim on the dash and doors, a tilt-adjustable steering wheel with built-in cruise controls, air-conditioning, and power windows, locks, and mirrors. The GS Convenience adds keyless entry and power-adjustable pedals. The LS Premium trim adds heated mirrors, electronic temperature control, a leather steering wheel, and a height-adjustable, eight-way power passenger seat with power lumbar support. The LSE model seats five and features two-tone leather seating surfaces and a stereo with adjustable speed-sensitive volume control. LS Ultimate edition includes a rear air suspension and audio and cruise controls mounted on the steering wheel.

Performance & Handling

The 2005 Grand Marquis has a standard 4.6-liter, V-8 engine that generates 224 horsepower and 275 lb-ft of torque. The LSE model and other models with the optional handling package get a more powerful, 239-hp version of the V-8 as well as dual exhausts. Both engines team with a four-speed automatic transmission and rear drive. The handling package includes a different rear-axle ratio for better acceleration, and all-speed traction control is included with higher-end models.


The 2005 Grand Marquis comes with a standard dual-stage front airbags and four-wheel anti-lock disc brakes with electronic brake-force distribution. Side-impact airbags are optional on LS Premium, LSE, and LS Ultimate models. A dual-rate brake booster automatically supplies full braking power during a panic stop. With the optional side airbags, the Grand Marquis earns a perfect five-star rating in all categories of National Highway Traffic Safety Administration (NHTSA) crash testing. The standard Grand Marquis receives four stars for driver protection in NHTSA side-impact tests and five stars in all other categories.
