I do not know what the author thinks communism is, but he seems to be using it as some kind of semi-racist semi-nationalist all encompassing pejorative, which was commonly used during the cold war.
It is funny when towards the end of the article he suggests (incorrectly) that this car is ok because it was really "a capitalist design" that was only "made by commies". First he is very much incorrect about that assertion. The Tatra 603 was ordered, designed and produced in Czechoslovakia, when that country was ruled by the communist party and was in the soviet block. But nobody in then Czechoslovakia would have referred to it as a "communist" country, not even the top communist brass.
But there is something here that will completely blow Mr. Locklin's mind away. If the car had been designed and produced under capitalism few years before the dates in which it was actually designed and manufactured, it would have likely been designed by the mostly the same group of engineers, and manufactured by the same workers that made the later "communist" car. You see there were a bunch of engineers working in a car factory, and then a bunch wars happened, and then all of a sudden they all become a bunch of "commies" and everything they made was "made by commies".
