The only repeat issue I've really seen with the old Nivas was rust as they allegedly spent months on snow-covered docks in Russia before being exported overseas, which ended up with them "coming with rust from the dealership".
I'm sure, however, that a professional day-to-day mechanic would have a different perspective on their reliability of course.
My only problem with the Niva is the fuel consumption, 19.6 mpg. Not something you'd want if you live in the EU. Otherwise it seems to be a quite reliable and repairable car. Also works with lower grade gasoline found in ex-soviet states.
My favourite Lada accessories are the rear spoiler for exceptional road holding and carpet on the dash for added luxury.
In 1976, VW started to make Golfs here Yugoslavia, in Sarajevo. Compared to other Eastern European cars like Yugo or Lada, VW golfs were solid. I still see many old Golfs on the roads here in Montenegro, and very few Yugo’s.
Yugoslavia is Eastern Europe but was neither NATO nor Eastern Block. The country stayed neutral, and they traded with both sides of the iron curtain. E.g. Americans have built a nuclear plant, Russians sold some military tech for e.g. submarines…
The body styling would be the only essential to be evaluated after.
