Not mine but hard to find - Hardtop Cover
 

I've been watching eBay for years waiting for an OEM hardtop cover to pop up. I don't think it's produced any longer but some dealers still have them if you want to pay the Porsche tax for a piece of fabric. Sure enough... two pop on eBay last week. One actually came with the trolley. I snagged that one but there is a brand new one still in the original box for $90. Sort of rare for used Boxster parts.
