Tags Renault. R4

We have seen it with the 2CVs: the prices have gone through the roof (and damaged the solar panels). We currently know of a ZGAN 2CV with a price tag of € 24,500. And the selling party happily states that there is very little room for negotiation in that asking price. Such amounts for such cars are madness. However, the Renault R4 is the 'better' Duck. A real driving car. And that is how it is often used. So what would happen to that?
