More and more I got the impression, that this car is an extreme rarity, maybe even the only existing survivor. When I google "Reliant Robin Jubileum 1978", the only pics and informations, which appear, were uploaded and written by previous owners of this specific car, for example:

and the -probably soon deleted: advertise:

Due the first text I know, that these 50 made Jubileum-cars has nothing to do with the UK-Jubilee-model from 1977.
They were made in 1978 for the 10th anniversary of the Dutch Importer Waaijenberg

To find out more, I've registrated myself for the German, the Dutch and the British Reliant-forums.

Well, maybe it's really an unique Holy Grail
