I think a modified Xfire with a Targa top might look ok and have the Roadster roll bars mounted on the back behind the seat just in case...I don't know though, you wouldn't lose the spine when the top is on but you'd have the open air.

but no sunroof, I had a moonroof in my prior car and rarely used it. It's either got to be a Targa or a Convert/Cabrio/Roadster and that's it.
