I got to see the the real Crossfire Convertable in person last week. We had a huge corporate meeting and they had not only the convertable version there, but also the SRT6 (aka supercharged amg motor) version.
I wondered the same thing about the top though. Every picture, video, and car I've seen had the top down. If I had to guess, I'd say its going to be a soft top.
I had my camera with, but there were signs all over the place that said photographs were not allowed. Since it was a unique opportunity to just be there, I figured I just not mess that up.
Sorry guys =)
