I wouldn't call the Crossfire with the SRT-6 engine option a "new car" since it's just an engine option. So, I think it makes sense that it is made available in the spring with the convertible following in the fall.
You can bid the 7 cubic feet of space under the hatch adieu with the convertible. I think that the Edmunds photoshopped Crossfire convertible is likely a good representation of what the convertible will look. It's been on their website for several months.
