The only trouble I get with my hard top is the rear attachments they are like a traditional. Bonnet catch. They are slightly bent (by the factory) so adjusting them is a s** basically if too loose they rattle & twang. Too tight and then they don't lock down fully & so the h'top "pops" up. Be aware if you get them too tight the release mechanism will not work so on mine you have to get at them via the spare wheel aperture. Also the side screens lay on the hard top so their fwd edge does not lie flat to the screen frame. On mine 1 side screen is also 1/4 in higher than the other.
Enough moaning the hard top is great keeps the cabin nice & cosy and looks great. (see gallery) they are cheaper in the standard ivory colour. Mine was ordered with the car & was the standard colour as it happens. They are also. Dry robust and have an interior lining.
Hope of help
