A tonneau cover is worth having even if it doesn't get much use, for all the reasons mentioned above. With the easy up on my Roadster, I prefer the hood cover over the folded hood. With that I always use a home made filler tonneau cover which fits between the hood cover and wind stop. In winter when solo I made up a passenger side only tonneau cover whichever dovetails with the filler tonneau cover and also has a hole so that I can retain the passenger headrest for symmetry.

Bumble didn't come with a tonneau cover so doesn't have the fasteners on the dash top. I made up a quarter tonneau cover to fit up to the rear of the seats, and had it professionally edged.
So - when I finally make my order, it will be mohair easy up and tonneau cover as a starter for ten.
