It will be very noisy with the roof up, the traditional hood will more than likely leak unless you fit it very carefully and probably fettle it, it takes minutes rather than seconds to erect ...so drive it as much as possible with the roof off! The heater is crude but effective. There is a lot of buffeting with the roof and side screens off...oh, and the chassis will flex!
All this makes me love my Morgan and the more I drive it, the more I love it...but a good long test drive is really needed to get a feel for it roof on and roof off.
