The Mercury Grand Marquis provides a durable and comfortable platform for roomy and smooth cruising. For the current incarnation, Mercury has kept the important aspects of the vehicle the same: large trunk, plenty of legroom, and a workhorse 224-horsepower 4.6L V8 engine. The base Grand Marquis GS comes with a split bench seat up front, the driver side being power adjustable. Anti-lock brakes are standard equipment as is a tilt-adjustable steering wheel, power windows and locks, cruise control, and remote keyless entry. The LS, starting at $4,660 more than the standard trim, includes traction control, 16-spoke aluminum wheels, fog lamps, and heated power mirrors. Interior add-ons include power leather seats and automatic climate control. Optional equipment on the GS includes traction control, fog lamps, and an alarm system. The LS is more configurable than the GS Grand Marquis. A handling package adds heavier duty suspension components, rear air suspension and bright aluminum wheels for $615. The Palm Beach Edition package includes a leather-wrapped steering wheel, heated power mirrors, cashmere leather seats and chrome wheels. A power moonroof is available as a $1,025 option. Heated front seats and a six-disc CD changer can be added as well.
