This being the only picture. How can this fall under your new policy of extremely good/mint, so no need to take out of the box, when you can't even see the model?
There are still plenty of Vauxhalls that haven't been produced yet, Viva Ha and HC, Firenza, Victor FA, FC, CD, FE. Ventura, Chevette, Mk1 and Mk3 Cavalier, various Astra's. Carlton's and Royale. Not to mention CF vans and later models.
