With the flying buttresses, I don't really see much of a difference in the open air experience. To me, the stylizing of this generation of convertible boils more down to whether or not you want to see the engine. One big plus is if you get the convertible, the removal of the top is powered as opposed to manual with the targa.
Another question I have is with the statement that the storage does not change between the convertible and targa with the tops down/off. Because the targa panel is stored in the trunk when removed, does the convertible place the same panel in the same location when the top is down?
Personally, the convertible sounds awesome, but I really like the view of the engine. I'm actually surprised they didn't put a window over the engine for the convertible.
