A revolving seat? Hm... wonder what that does for safety. Honestly, I don't see the enticement in that... you'd have to literally turn backwards when getting into the car -- is that natural?
Seems I remember some Chevy product having swing out seats like that. Monte Carlo maybe? Girl friend had one and as I remember it, the seat would not turn with the key on. Might be nice for some of us old farts. :-)
