My VW wasn’t brand new...and to tell you the truth I cant remember what Year...I bought it..
It was the 6o’s! ....Prior to My coming to my senses.. I hasten to add.
It had an oval rear window that I remember well.
On Volkswagens the one piece oval rear window was on the 1953 through 1957 models. Before that it was a two piece oval going back to the Nazi KdF-Wagen. In 1958 the rear window was widened to a rectangle shape & stayed mostly the same until the last Beetle with U.S. specs which was the 1977 model. They were assembled in Mexico & Brazil for years after that but that’s stopped, too.
