Correct me if I'm wrong, the Mustang has to be stationary to put its top down and the covers that go over the mechanism have to be put on manually, don't they?
That would be a big selling point for me.
I also hated the 5th gen convertible with the top up. You could see the "ribs" underneath the cloth and it completely ruined the look. The 6th gen top is much better looking for sure.
