I highly enjoy this guy taking apart and fixing his Trabant. There's something funny about owning a GDR car in the US because all the parts are only available in Europe and the service manual is in German https://www.youtube.com/playlist?list=PLzV2uljPvyAeEgAEgwYNfKKoFGx2LSejt
he's also done some other fun stuff with it like try to race rallycross with it https://youtu.be/x5AR9vvCfKM
it's also fun because the Trabant is a car so simple that you can literally just take it apart and see how it works
