I am actually an online acquiantance of Ed Hughes, he is friends with a lot of people I am friends with. He owns the blue and yellow (OGV 411P) one used for the modelling of the ZAZ in cars 2.
I was also considering buying one a few months back.
I recognised it instantly, thought it might have been a NSU Prinz as well.
I've got to find another one now.
Here you go, try this.
