Stan, Patrick and Snotty... you are all correct... at least to a point. The manufactures are to blame for much of the confusion... they took liberties with terminology back to the 1920's and 30's in efforts to drive sales, draw attention and stand apart from their competitors. They have been doing this every since, so your factory literature will often incorrectly label a car for whatever good they thought that would help their brand.
Evolution of language has pretty well changed meaning or use of so many common terms. The manufacturers just mucked it all up... like this

4 door coupe... WTF... lots of cars called Roadsters in factory literature too, because they were 2 seater drop tops.
To me... if you said someone had a "split window", that had meaning. To say '63 corvette, split window told me it wasn't a convertible... but you did repeat yourself as far as I'm concerned. My parents bought a 1972 Dart new... it had a Swinger emblem on the trunk... I was young and wondered where the swing was supposed to be... Over years I noticed a few with that emblem... not really that many. Now look at CL or EB and see how many idiots think its a Swinger... some don't even seem to know its a Dart. Swinger wasn't even a sub model just a meaningless emblem. Somehow the flipping idiots think it increases value.
