The Grand Marquis is a full size sedan that has earned the honor of being best selling Mercury vehicle ever produced. However, the 6 passenger 2008 Mercury Grand Marquis is sadly outdated and outclassed by the competition in just about every respect.

This large sedan is rear wheel drive and powered by a 4.6 liter V8 engine that delivers 224 horsepower and is controlled by a 4 speed automatic transmission. There is more than enough power to allow for quick acceleration, and highway rides are relatively smooth and comfortable. The EPA estimates fuel ratings at 15 MPG in the city and 23 MPG on the highway, which is within average range for a full size sedan, but essentially the same fuel economy ratings apply to a few other cars in this class and they all produce much more horsepower than the Grand Marquis.

The first of two trim levels is the base model GS, which is complimented by the upscale LS. The GS comes standard with 16 inch wheels (the wheel covers are faux chrome), keyless entry, full power accessories, air conditioning, automatic headlights and stereo with CD player. The Grand Marquis LS replaces the 16 inch faux chrome covered wheels with 16-inch alloy wheels and includes the features found on the GS and adds leather seating, automatic climate control, a leather-wrapped steering wheel, a fold down armrest in the rear, an auto-dimming rearview mirror, fog lights, heated side mirrors and an overhead console that provides access to a compass and Homelink technology. Options for the GS and LS models include a sunroof, heated leather seats and a premium audio system with in dash CD changer.

With a perfect 5 star safety rating for front, rear and side impacts awarded by the National Highway Traffic Safety Administration for the LS model, driver and passenger safety is one of the 2008 Grand Marquis's strong points. The GS is not as well equipped but still earns a respectable 'Good' rating from the Insurance Institute for Highway Safety. Antilock disc brakes are standard on both models, while the worthwhile enhanced traction control feature is standard on the LS and optional for the GS. Overall, the Grand Marquis offers a fair amount of comfort and convenience and is a safe, reliable vehicle. Not a bad purchase price, but those who continue to do their research will find similar vehicles with more luxurious comfort and convenience features, additional horsepower and a more modern and attractive design both inside and out.
