I found this on another site, maybe this could be an option for our RX8's

New option package for next year. (http://www.rinspeed.com/pages/cars/splash/pre-splash.htm)

That's nice but if they made it submersable... "The Spy Who Loved Me had" had that beautiful Lotus, I think it was a Lotus anyway.

Oh and it would need to come with a missle launcher and torpedo launcher.
