The novelty of this sunroof never wore off. It was a canvas/rubber type and was surprisingly water tight. Yes it would leak if you sprayed right at it with a water hose, but in a downpour it would not. I had it open anytime it was not raining. It totally opened up an otherwise cramped cabin. It did eventually crack and leak. By the time I found a good replacement top, this car was gone.
For all the positives, I don't think I could ever bring myself to cut the roof on my current sedan.
