This is the beginning of a new series of puzzles, dedicated to limited editions of mass-production cars. It won't always be as easy as it seems, because limited editions are sometimes poorly documented, difficult to tell apart from the regular versions and often market-specific.
So, for 1 point : year and name of this limited edition.
Maybe Citroën C5 Sillage, from 2005.
Indeed. It was unveiled at the very end of 2005 so it was rather a 2006 model. One point for you anyway.
Original scan.
Correct - I have December 2005 as the release date, and never thought you could be expecting the model year rather than calendar year.
