Mercedes-Benz C-Class Used Car Buyer’s Guide: 2003
All-wheel drive was added to the lineup for the sedans and wagons running the normally aspirated engines (in other words for everything except the C230 Kompressor and the C32 AMG). The C320 got a six-speed manual option and the supercharged 2.3-liter engine was also fitted to the sedan.

To improve the handling and braking of the C230 Kompressor Sport Coupe, 17-inch wheels and high performance tires were specified. The model also got a three-spoke fat-rimmed sport steering wheel, a leather-wrapped gearshift knob, an aluminum pedal set, and a larger chromed exhaust outlet than the standard car used.
These upgrades were also applied to C-Class Sport sedans, along with new four-piston calipers for the front brakes and drilled rotors. Increasing the performance quotient were a sport shift manually operable transmission, a lowered sport suspension system, a free-flow exhaust system, and a set of all-new five-spoke alloy wheels.

C-Class models were formally divided into Sport and Luxury models for MY’05. Basically, the Sport Package became a trim line unto itself. When cars were not equipped with it, they took on the designation “Luxury”. (C320 vs. C320 Luxury for example.)
The C55 AMG replaced the C32 AMG. For the C55, the AMG team fitted a normally aspirated 5.4-liter V8 to the C-Class, one capable of generating 362 hp and 376 foot-pounds of torque. The engine was paired with a five-speed automatic manually shiftable automatic transmission.
