Year-to-year Changes
In 1999, automatic headlamps were added, and the Handling Group removed the speed limiter. In 2000, an interlock was added to prevent shifting from Park unless the brake was pressed; and tether anchors were added to the rear shelf for child seats. The year 2001 brought more changes, with an optional luxury group that included an automatic dimming driver-side mirror and supplemental side airbags. A more advanced EVIC (trip computer) was made optional. The 300M also received new jeweled taillights.
In 2002, electronic brake distribution was added to the antilock brakes; a new computer combined engine and transmission controls; LATCH tethers were built in; and “natural” evaporative emission monitoring was added. Midyear, the 300M Special was introduced with a 255 horsepower 3.5 liter engine (running on premium gas) with 258 lb·ft (350 N·m) of torque, and a 3.89 final drive ratio. The 300M Special also had high intensity discharge headlights, faux carbon fiber trim, high performance brakes, and optional Michelin Pilot Sport 245/45R18 performance tires. A new grille design was also introduced. Also, not as powerful as the 300M Special but much more rare, the 300M Pro-Am appeared in 2002. It included an infinity system with subwoofers. 2 toned leather was also added in the Pro-Am edition.
In 2003, new colors were added, a six-disc CD changer replaced the four-disc changer, and the changer controls were added to the stereo. 2004 brought optional Sirius Satellite Radio and an optional stereo with DVD-based GPS navigation.
