Welcome, Mercedes-Benz W203 Owners
Your home for everything Mercedes W203 including parts, maintenance, upgrades, and specs.
The Mercedes-Benz W203 Chassis was sold in the United States from 2002-2007, and is the third generation C-Class following the W202-chassis. The W203 shared its platform with the CLK-Class (W209 -chassis), and saw a host of engine options over a distinct period of growth for the manufacturer; W203-chassis cars can be found with everything from the supercharged M111 of the late-1990s and the subsequent M271, to the M112 V6 and the M272 later carried over into the W204 C-Class and our C300 AER Endurance car, and even to the venerable M113 V8 stuffed into the nimble C55.
The W203 offered a compliant and comfortable entry vehicle into the Silver Arrow lineup at a reasonable price, and saw a host of mid-production revisions and alterations that culminated to make the W203 C-Class a great pick on the used market today. With several different variations on 4-cylinder and 6-cylinder powerplants available in this chassis as well as a few factory-equipped manual transmissions, secondhand buyers can easily purchase a W203 specifically tailored to their tastes and needs.
