That's what I do if I won't be driving the car frequently.

After cleaning up the spring/clip and slots, it slides on and off quite easily. The first time removing it, 40 years of time made it a bit hesitant to move; a little PB and a quick hit of lube makes it a quick in and out now.

Added Rolling up Info:

For rolling up the cover, it can be a bit bulky depending on how windy it is when I'm rolling it up. If it is windy, once I get the front or back slipped off from under the bumper, the cover wants to fill with air and lift off the car on to the ground, so I just do a loose roll and it is quite bulky.

If it isn't windy, then I have the luxury of slowly slipping off the front and back elastic areas, then folding up the cover, one side at a time, so it ends up being in thirds, over the length of the car. I fold up the entire passenger side, then the entire drivers side over on top of the previously folded side, so the cover is 1/3 as wide as it is open. I then roll it up from the back, tightly, and end up with a snug roll that's about 3' wide and 18" in diameter. it fits up against the back of the rear seat, between the rear shock towers, leaving a ton of space to use in the massive trunk.

Loosely rolled, between shock towers... (if snugly rolled, it is about half that size)
