The facelifted Renault Master II and its clones were sold from November 2003 onwards (fr). In IMCDb habits, that means a 2004 model year.
I'll manually change the 2 Renault⁽¹⁾ and 3 Nissan that are set for now as 2003 models. Could the 16 Opel Movano be directly changed in the Db?

1: 5, in fact, but 2 are apparently 2003+ Brazilian built models, and 1 a British "former face model" certainly identified thanks to the DVLA.
