The Vega was the worse car I’ve ever seen.
In 1972 at the dealer I got into one with the salesman to do a test drive, I didn’t even put the key in before I said this car is pure junk and told the salesman I don’t need to drive it, just getting in showed me this was junk, we both got out and I left.
I bought a Toyota Corolla instead.
I lived in Germany in 1975 and drove an Opel 1600 which was a fine car and kept up with most of the cars on the autobahn. Had enough room for my family of 5 to tour europe. Flew home next to an executive from GM and asked him why they didn’t just import that car since they owned Opel, instead of building the Vega and the Chevette, both crappy cars. He gave me a lame non-answer about parts and manufacturing issues. They didn’t know what they had.
