The facelifted Mercedes-Benz C-Class W203 was introduced in mid-2004 and remained in production until 2007. It featured updated front and rear bumpers, new headlight and taillight designs, and a refreshed interior with higher-quality materials and revised instrument clusters.

Technologically, it gained improved versions of the COMAND system, as well as updated Audio 20, Audio 50 APS, and COMAND APS units—offering options like CD changers, DVD navigation, and better integration for mobile phones.
