I think that photo might be the production prototype car. IIRC, in the photos I've seen of it, it's SSB with a Cedar interior, often with Euro plates. The interior in particular (which might be the same as that shown below as a disembodied styling buck) is clearly different from what actually became production - brighter silver color (nicer looking, but probably a reflective PITA), carbon fiber instrument panel rim, and different switchgear, radio, vents, steering wheel trim, etc. Although I'm not certain, this may be an underhood photo of that car. It's very close to the production car, but different enough to be pretty intriguing - for instance on the interior photo below there's another red button below the hazard light switch that replaced the start button of the original concept car. (Awesomely labelled simply, "Go!")
