They also both employed Italian management at some point 😉
The old Zastavas have the characteristics of old Fiats - you can rev them till the valves poke out of the bonnet and only then change gears 😁 And most didn’t have a rev limiter, so with a long enough downhill section they reach much higher speeds than intended 😁 Of course if you do that in one where only the handbrake still has some functionality, it adds to the excitement 😂 First hand experience 😉
