Does anyone know whether it is reasonably straightforward to replace the electric fabric roof on the Seicento? I have located a replacement but I'm not sure about what is involved in removing/fitting. I image it comes out as a unit (?) Any advice gratefully received.

You could always ask the person you're buying the replacement from, they'll know how easy it is to remove

Edit: Is it this one https://www.fiatforum.com/classifieds/showproduct.php?product=32249&cat=all ?
