I have a almost brand new setup hardtop assembly, has motor and all the wiring. It was dented at the dealership, small dent. Has chrome package, black in color very nice, ready to install. Follow link below, goes to my ebay store where can find all info and view the pictures. this is a complete deal, not just the frame. I believe the dent could be easily popped out with the right tools and knowledge.
Any problems with link, My ebay store is 2CheapAutoParts
I have other parts, bmw modules, ect as well as many other brands in small parts
