EVERYBODY is a noob at one time. Don't sweat it and don't apologize for it.
Coupe is a "fluid" auto term...meaning pretty much whatever the automaker wanted it to mean. Usually, a coupe has a 'post' between the front and rear side windows and a hardtop or sedan doesn't have a 'post'.
I'm not a "founding member". I'm just an Oldsmobile nut with a lot of time on my hands!
