I would modify the cover so the car could be driven with it in place for that day you get caught in a sudden downpour. Always possible. I would also waterproof as much of the electrical as you can....again, just in case.
I have seen many say they will never drive in the rain.....but you just might be caught in it or you may not drive it very much if there is a cloud visible.
The roll bar....just have one built to fit.
