well, let's see...
I can CONVERT my hardtop Jeep to a soft top, and then I can remove the side and rear panels and roll them up, and then I can fold the front of the top back, or fold the top down completely, CONVERTING the Jeep to a fully open vehicle.
Then, in just a few minutes, I can have the Jeep fully enclosed again.
Seems to me that meets the definition of "convertible".
Yes, it is more work and time than just pushing the button on the PT Cruiser, but the Rubicon WILL convert to a fully open vehicle!
