2010 marks the end of the line for the Grand Marquis. It has served for many years as the symbol of old school American luxury. A large, low RPM V-8 driving the rear wheels, with suspension so soft that it floats over bumps rather than absorbing them. This type of ride has appealed to an older crowd for the full 30 years that platform which powers the Grand Marquis, and its sister cars, the Lincoln Town Car, and Ford Crown Victoria, has been in production. For the last several years, it’s styling has remained fairly stagnant, which to its buyers has been a good thing, as they are typically a demographic who doesn’t like the idea of new and different technology being added to their vehicles.

There is only trim level available at present, the LS. While it has all the features that its loyal buyers have come to love, it goes the way of the dinosaur it is taking its amazingly underpowered engine along with it. A 4.6 liter V-8 making 224 HP and mated to a 4 speed automatic was all that was offered to push this large sedan.

The Grand Marquis enters its final year without any changes.

The Grand Marquis’ sheetmetal has been unchanged for years and its close link with the Crown Victoria means it can be mistaken for a police car from a distance or at night.

The Grand Marquis’ interior has not been updated in ages, but it’s one of the few cars on the market offered with a front bench seat and it features a cavernous trunk with 20.6 cubic-feet of space.

The Grand Marquis’ 4.6L V-8 packs just 224 hp but a more-impressive 275 lb-ft of torque, though both figures are easily best by many modern V-6 engines. A four-speed automatic is the only transmission available, and yet the powertrain returns a relatively-good 24 mpg on the highway.

The Grand Marquis features four airbags as standard equipment — dual front and dual front side — plus seatbelt pretensioners and traction control.
