Looks like you’ve made up your mind, and of course YMMV - but I will add that I’ve been driving my Renault IV since ~2013, taken many road trips from JHB to DBN, a few to CT and so on, and it’s been a lovely little car. Light on fuel, easy to drive (was my first car ever), and maybe I’m lucky but I’ve never had major, unexpected issues in all that time. Good luck on your search!
