Yes I thought about that one too. A real icon of a car.
Long production run too.
Probably my favorite model from my favorite brand with an engine from my favorite automotive designer ever
But tough to beat the Golf GTI.
One car per decade is very little of course.
And in the 60's there also appeared a sportscar with an air cooled engine in the back that turned into an icon
But tough to beat the mini
So many choices
I wanted 1 car per decade, and failed at that at some point
...and in the 50's another iconic sportscar with plastic body was born in the US...
mechanically pretty prehistoric compared to that DS though
