2006 Mercury Grand Marquis review: Our expert's take

Vehicle Overview
Mercury’s Grand Marquis and the similar Ford Crown Victoria are the only six-passenger rear-wheel-drive sedans sold in the U.S. with V-8 engines and traditional body-on-frame construction. The 4.6-liter V-8 produces either 224 or 239 horsepower.

For 2003, Mercury’s Canadian-built full-size sedan got a new frame, suspension and steering system. Equipment revisions and a mild face-lift highlighted updates for 2004.

Four Grand Marquis trim levels are available for 2006: GS, GS Convenience, LS Premium and LS Ultimate. New 16-inch, 16-spoke machined aluminum wheels are standard on LS models. All Grand Marquis sedans wear a fresh grille, front fascia and headlights. LS sedans now include an overhead console with a compass, map light and universal garage-door opener.

According to Ford Motor Co., every Grand Marquis since 1996 has earned five-star ratings for the driver and front passenger in frontal-impact crash tests conducted by the National Highway Traffic Safety Administration. With side airbags installed, the sedan has also earned five stars in side-impact testing.

Styling modifications to the grille, headlamps and taillamps are evident on 2006 models. Lightweight hydroformed steel sections are used for the front rails of the full-perimeter frame. Standard 16-inch wheels are installed. An optional handling package for the LS sedan includes a rear stabilizer bar, rear air suspension and aluminum wheels.

Measuring 212 inches long overall, the Grand Marquis rides a 114.6-inch wheelbase and stands 58.3 inches tall. Rack-and-pinion steering includes speed-dependent variable assistance. Options include a moonroof, fog lamps and a full-size spare tire.

All 2006 Grand Marquis models can hold up to six occupants. The trunk’s cargo capacity is 20.6 cubic feet. Liftover height is 26.8 inches, and a trunk organizer is optional.

Standard GS equipment includes a CD stereo, an eight-way power driver’s seat with lumbar support, air conditioning, and power windows, locks and mirrors. The GS Convenience adds keyless entry and power-adjustable pedals. Heated mirrors, electronic temperature control and a power passenger seat go into the LS Premium sedan. The LS Ultimate edition includes a rear air suspension, a wood- and leather-trimmed steering wheel and a dual-mode audio system. A Limited Package for the LS Premium includes two-tone leather-trimmed seats, myrtlewood-grain trim and nine-spoke chrome wheels. Heated front seats are available.

Under the Hood
In standard form, the 4.6-liter V-8 develops 224 hp. Models with the optional handling package get a more potent 239-hp version of the V-8 with dual exhausts. Both engines team with a four-speed-automatic transmission. The handling package includes a different rear-axle ratio for improved acceleration from a standstill. All-speed traction control is included with higher-end models.

All-disc antilock brakes incorporate electronic brake-force distribution. Side-impact airbags are optional. A dual-rate brake booster automatically supplies full braking power during a panic stop.

Driving Impressions
Fans of traditional rear-drive sedans don’t have many choices today. Fortunately, the Grand Marquis is a reasonable one, offering a comfortable ride, satisfactory performance and ample space. These attributes, however, are accompanied by tepid handling. Ford’s Crown Victoria delivers the same benefits, but the Grand Marquis contains more comfort and convenience features for the extra dollars.

Awesome boat

If you're looking for a big comfy boat that you never have to work on, this is it. The interior could've used some better plastics, but the dash is straight out of the 90's, in a good way, same as a Vic. The interior holds up well, the 2.73 rear end gives you good highway milage (Got 27 once going from STL to Baltimore, usually 25), plenty of get up and go, and if you want a bit better handling, ADTR has a bunch of quality suspension parts that makes this boat ride flat. The 4.6 2V is one of the best motors Ford built in regards to reliability, especially with the PI heads that pretty much fix the spark plug issue, the variable rack makes steering much more "sporty", if you can call it that, than the previous reciprocating ball, the 4R75E trans is good if you actually service it on time, and if you do have to fix anything, parts are plentiful, cheap, and east to get at, and since every part is the same as a vic besides the the front end and trunk lid you can find them at any junk yard. Bought mine for 7,500 witj 50k miles. 10/10 would recommend.


Grand Marquis

I have a 06’ with 57k. I went from being a truck guy to this smooth as silk heavyweight. It’s no hot rod but will cruise all day at 90 like it’s nothing. Everything else out there today is cheap plastic rough riding crap.


Love to get another one

I never would of trade it in, except for the high mileage it finally accrued. The ride and power was terrific and it rarely needed a repair. Upon trade in it sold quickly. The mercury marquis was discontinued in 2010 and is always valued by mechanics and dealerships for reliability and quick sales.
