Combo [C] (2001-2011)
The second generation Vauxhall Combo (C) was launched at the Frankfurt Motor Show, in September 2001. While most competitors severed their connections with their subcompact brethren, Opel decided to base the vehicle on the Corsa again. Production of the Combo C ended in the end of 2011.
Early models (2001-2004) use an ISO plug while later vehicles are on Quadlock. The easiest way to confirm is to remove the factory radio and physically check.
