back to your question, Joest. Yes, I have one photo of a Polski Fiat made by Jiangbei. The car is named Jiangbei JJ 710 and the picture is dated 1986/6/15. I suppose they have made only one, I never saw one in the streets.
In the streets I made pictures of a Meiluo JJ 7150 which is a KIA Sephia, a Meiluo JJ 7090 which is an Opel Corsa, a JJ 7080 Alto, a Shenjian JJ 7050 also named JJ 720 (Daihatsu Cuore/Subaru Jumbo). Yes, China has a rich car history....
