My belief is Dodge will continue to produce the Challenger as long as orders come flying in for them, but they will cut them off eventually as the car is supposively a limited production run car per MY year. What I am hoping for is that the Challenger stays in production for at least 4yrs, hopefully more. As for a convertible version, it might not happen until after the first MY production run happens. I do think they will come out with it, but time will tell.
