Well, I've had problems with my convertible and was wondering why I didn't buy a couple instead, until I finally converted the top to a manual. I disconnected the convertible top transmissions and just use the mechanical latch above the windshield, and no more problems.
Whats great about driving a cab is that open cockpit feel while taking a spirited drive on a curvy road. I drive it with the top down with temps in the 20's and only put the top up when it rains. BTW, the top has never leaked.
