Huh? Okay, to the subject at hand:
I've driven both, mine, and a SRT6 Coupe. The Coupe was more quiet. The Roadster had more headroom.
Other than that, I couldn't tell a difference.
They are both great cars.
I'd like to have a Coupe in addition to the Roadster.
I enjoy dropping the top, having a vert was key to my purchase.
You might want to find a Roadster, drive it, and see if it is worth making the switch. Good luck.
