Also available are two long-wheelbase models: Executive L ($44,245) and Cartier L ($50,700) are six inches longer overall. The longer wheelbase provides more headroom for all passengers and nearly six inches of additional legroom for those sitting in the rear seat. Both long wheelbase models have larger rear doors and special rear seat amenities that include audio and climate controls, power outlets and a button to slide the front passenger's seat forward to create even more rear legroom. Cartier L models have heated rear seats.

Executive is a fully equipped luxury car minus some of the wood and leather trim items and standard equipment that pertain to the Signature and Cartier series. The 2003 Executive comes with a long list of standard equipment that includes brighter headlights, larger 17-inch alloy wheels, a new analog clock, new interior storage compartments, dual-zone climate controls. All Town Cars come standard with CD players, but a trunk-mounted six-CD changer is optional.

Signature and Cartier models come with an even higher grade of leather on the seating surfaces. Signature and Cartier versions have upgraded Alpine audio systems. The Signature version gets a wood and leather-wrapped steering wheel, premium leather seats (heated in the front) with a memory feature that positions the gas and brake pedals in addition to the seats and mirrors, rain-sensing wipers, 20-ounce Shiva pile carpeting, special 14-spoke wheels and a new extended rear park-assist system that uses both ultrasonic and radar sensors. A power-sliding glass moonroof is optional.

Cartier models add a power trunk lid that opens and closes at the touch of a button on the key fob. Cartier versions also have a specially outfitted trunk with a large, removable, covered storage bin that is optional on the other models. Cartier comes with fog lamps and nine-spoke alloy wheels that give it a more formal appearance. Cartier versions have seats and floor mats embroidered with the familiar Cartier logo as well as special headliner and roof pillar fabrics. The Cartier versions come with high-intensity-discharge lamps, which are optional on the Executive and Signature versions for $435.

Town Car options include the Lincoln Vehicle Communication System ($1,295) with a hands-free Motorola Timeport phone with such personal information services as news and stock quotes. Two-tone paint schemes will cost you $260, and white pearl paint is $375 extra. Whitewalls, on all but the Cartier L, are $105.
