I've seen one or two roadsters for sale that apparantly have both the electric soft-top AND the hard top available, so I was wondering if this is something that only works one way, or can a car originally setup as a hard-top have a soft-top retro fitted?

My assumption is that the hard-top merely uses all the same fitting points as the removable guide rails for the soft-top, and so fitting a soft-top to an original hard-top would 'less than a simple job'?

Going to see a very nice looking hard-top over the weekend, but would not say no to the ability to fit a soft-top for the summer months.
