No, it was a separate option. I have had cars with just the fold down back seat and presently have two 360 Dart Sports with the fold down back seats and sunroof. I have NEVER seen a sunroof car without the fold down back seat, though. Of course, there were the Swinger with the sunroof but cannot have fold down back seat. I'd like someday to have my cars decoded by Galen to see how many cars actually came with sunroofs. I don't think there were many.
