I've had my car for over a year now and mine is still wrapped in the plastic from the factory. I'm not sure I'm ever going to use it and wish I hadn't wasted the $$ on it.
One nice thing about the convertible tops on these cars is the manner in which the top folds down. When its down the outside portion of the foward most outside section of the top is what is exposed. It provides a finished look as it doesn't show the inside of the top headliner like on most vehicles. You may want to reconsider the cost of purchasing one if you haven't already.
