Yeah it was a pain from memory,not that exact colour but Citroen do an almost identical one and we had fun and games with it back then.
If its just bumpers/grille/side skirts I reckon you'll get away with it as they all have gaps between panels as standard and often bumpers and plastics look a touch different anyway.
If it were a door or wing I'd be more concerned that you'll near enough need to blend the whole bloody side!!!!
