>>9181840It's called polonez tso
it was one of the most popular general purpose cars produced in Poland during the 70s and 80s
basically an equivalent of Russian Volga
As of you can get those cars relatively cheap for about 3000-4000 PLN depending on condition though whether you'd be able easily to find an offer outside of Poland
There's also a revision from late 80s called polonez caro with more HP
