Sorry the higher the asking price the higher the bar. As for slumming it, I've driven plenty of convertible cars that were not meant to be minus a rigid roof. The C4S reminded me of them. I'd add one convertible M3 to that as well.
However, I have driven properly set up Cabs and C4s that were totally different but that's not the same in my book because of the expense required to make them what other much less expensive cars are right out of the box.
