no, most people will probably have never heard of it, it that rare. if i give any clues it will become too easy. it is a pre 1975 car though, that should narrow it down a bit.
you didn't deny it was a vauxhall though, you just said it wasn't a vx220. so is it any kind of vauxhall? is it a concept car? if it is then it's not allowed (see post #1)
