The way I think the registration number thing works is that it continues to be assigned to the original car until dvla hear differently, as in you inform them that it's been scrapped or exported for example.
Let's face it, if the number had been put back in the pot and was now on another car it would show up on a search as on whatever it now belonged to via a private plate transfer, as its still out of the system then I'm confident it's still assigned to the Flaminia.
Mike, if you are interested then I can hang onto it if a deal can be done, until the summer in reality. Once we get to March I'll be bringing either the Dedra (assuming I get it finished...) or the integrale home so that will free up space to get at my Flavia. Not ideal, but I don't mind storing it for a while longer if someone with the needed enthusiasm comes along. The right buyer to take it on is more important to me than getting it gone quickly, although every time I think about it going the more I think about keeping it! But reality is that I have the Flavia along with 3 other classics so how many can I really justify keeping.. So a new buyer is preferred
