I've owed both, a manual coupe and currently the rag top , but with auto. I don't regret the switch, light to light the weight difference isn't that bad, and there are only a few places you will hit the limiter, and it is removable in the tune.
We do a yearly trip to the mountains in BC and having the top down, the echo of the car off the mountains, and 600hp when you need it....
I agree with the above comment, add a roto-fab and pulley, sounds awesome with the top down. Oh, and headers, can't forget those...
