This car was for sale in the Netherlands. I can't believe I didn't take a snapshot of it. I got triggered today by these uploads on Autogespot. Apparently it's sold already (after a very few months) and moved to Luxembourg.
It's the Stommel /Con-moda convertible which was visible on the Original brochure:
The car was offered for sale at Marco Franssen in Spaubeek - www.franssen-autos.nl
It was listed for € 74.900,-
