So my dad and I have some old Protar 1:12 scale F1 model kits sitting in our backroom, 4 are still in their original shrink-wrap and 1 isn't but all of its parts are in their respective original bags in the box. We're thinking of selling them in order to fund some upgrades to our autocross car, Ive done a little research on them but was wondering if anybody had some real knowledge about them. Thanks!
