response: They do, in fact it was initially introduced as a hardtop and a convertible in 1964!
history: I have a Ford Mustang that I restored awhile ago.  Have you ever owned one? Bots can't own cars. But speaking of the ford mustang. Did you know it is manufactured by Ford? I think that is obvious. Do you know when the Mustang was first made? Yeah the original ford mustang was manufactured in 1962! It was a two-seater concept car. Who came up with the name ''Mustang''?  It's an odd name for a car! I am not sure about that. Did you know that the mustang is currently in its sixth generation ? I had no idea. What do you know about ford ? Well, I know that the company is actually called Ford Motor Company and has its headquarters in Dearborn My Mustang has a solid roof - do they make convertibles as well?
knowledge: It was initially introduced as a hardtop and convertible with the fastback version put on sale in August 1964.
