I'm tempted with a hard top for my Aero 8 S4 just for the winter months. I could tell you that it would help look after the hood or it would offer better security. The truth is I just like the look of the hard top on an Aero 8. My concern is that the folded hood obscures a good percentage of rear view vision which, when the hood is down, doesn't matter but does the folded hood obstruct any of the rear window when a hard top is fitted.
