Even though I have a Diablo Roadster, I would recommend staying with the coupe. After driving around with my top off I started to get uncomfortable with everyone staring at me. These cars get so much attention that I perfer to keep the top on and the dark tinted windows up. Plus if you go somewhere you constantly worry about your car being open from the top. Also, depending where you live- the summer and winter temperatures limit your enjoyment if its too hot or too cold.
I never take my top off anymore......
Im in Texas, and with 106+ degree summer days, its nice not to have the sun frying the top of your head....
