Hi Cole, The mk3 Expression was (if I recall from my days in sales) around J or K plate, so 1991/2, in a light metallic blue or red, had the Cavalier LX alloys and similar black/red striped seat trim to the Astra SX. A 1987 Cavalier could have been added with the expression graphics by a car dealer... We badged up some Corsa's as " Monaco " as we fitted aftermarket TSW monaco wheels and put the SRI spoiler on. Good luck with the viewing, be good to see the pics
