Thanks for sharing the video, OP.
This brought back memory lane for me.
While living in Germany, my parents bought a used German spec 1977 BMW 316. I learned to drive in that car. The color? Yep, the same green as in the video!
I have fond memories of that car. I ran that car into the ground, lol.
In 1982, my parents bought a brand new left over 1981 German spec BMW 320, in the beautiful metallic brown color, with tan cloth interior. It was a basic car with the steel wheels, but that car was so refined compared to our old '77 316.
I remember seeing a few BMW 323i's in Germany, thinking that car was the cats meow. It was so cool with the four headlights, and dual exhausts, one on each corner. What a car, back in the day. In its day, it was one of the fastest cars on the road, no kidding!
Technology has come a long way...
