I have a Nissan 350z roadster. I love it. When the temperatures are just right, there is no greater joy in driving that with the top down. I found with my Z that I get better gas mileage with my top off than with it on, even when I'm not running the AC. Therefore, unless it is 80+ or 65- outside, my top stays off. In the hot North Carolina summer, it is usually too hot to ride convertible. It isn't the heat, it is the sun beating down on you which makes you sweat.
My Z has a cloth top. Some idiot decided it would be a good idea to put a knife hole in it. Needless to say, I was ... angry. However, even with the knife hole, it never leaked even in the heaviest of rain. My insurance replaced my old faded top, so it all worked out in the end even better. To prevent fading again, I'm not using car wash fluid or car washes to clean the soft top.
The nice thing about the Z soft top is that the roof bars are very close together. You would have to be skinny as a rail and very nimble to cut the top off and get in.
