Corsa [C] (2000-2006)
The Corsa C was revealed in 1999, and introduced to the European market in October 2000, and the facelift arrived in August 2003. This generation of the Corsa was a huge success for Vauxhall in the United Kingdom, which is the most popular supermini and second most popular car overall in 2002, 2003 and 2004.
For the audio, pre-facelift models (2000-2003) use an ISO plug while later vehicles are on Quadlock and Fakra. If unsure, the easiest way to confirm is to remove the factory radio and physically check.
