Yeah, Škoda wanted to make very high quality cars all the time. The first pic was supposed to be sporty version of peoples car with engine in front rather than back (but with rear-drive). They were supposed to make 100.000 cars. But politburo defunct the project :(
But, there were still small shops like Metalex wich took parts from big factories and created sports cars for rallying, racing etc. The second pic is the car that was developed in 1980s but was released in 1990s. That car used V8 engine of those Tatras >>4509
wich were used as highway patrol and transport of important people. Also last 3rd pic is that V8 engine.
Sometimes I wish the planned economy was a little bit more relaxed. There was always a potential. Now Tatra just makes trucks and isnt even Czech anymore….
