The windows on my Challenger are frameless and it's the quietest interior on any car I've ever owned. If the window seal is done correctly, I don't know how much difference a window frame makes.Frame less doors are lighter, and they look great with the top off. BUT, with the top on the framed door has a better seal with the window. Its easier to seal the top of the door to the top than the top of the window to top. I think some people will not like it, because I do see it having some wind noise, especially for us people who actually take the top on and off a lot.
