If I may add, this ability to open and close the top without leaving the JL makes it desired on this attribute, along with Bestop's Sunrider product for hard tops, over the OEM soft top. Clearly there are other factors though, like the OEM's soft top;s larger cargo area.Also, I love being able to flip the front seat portion back or bring it forward at a light.
People who do highway driving in areas known for summer thunderstorms tend to agree. Such driving sometimes makes for less places to safely pull over, get out, and close the OEM top as a rapidly moving storm's speed is compounded if traveling in the opposite direction to your high speed movement.
Of course (with money) the later can also me addressed with the OEM power top and Mytop's soon to be released soft top for the JL; the latter featuring a similar fast back look to Bestop's Trex aftermarket soft top offering.
