A favorite of retirees and limousine companies, the RWD Town Car offers traditional full-size sedan room and comfort. As expected, the standard 239-bhp 4.6L V-8 and 4-speed automatic provide adequate performance for a 2+ ton sedan. The base Signature model has minimal standard features, and is best suited for the fleet market. Upper trim level Town Cars can be equipped with a THX® CD audio system, power adjustable pedals, navigation system, rear heated seats, and power trunk lid. The Town Car Signature L has a 6-inch extended wheelbase for more rear legroom.
