A guy who owned one in Palo Alto used to park across the street from my work a few years back. It was definitely pretty cool looking, in terms of the aesthetics. The outside panels DID consist of a recycled heavy-textured plastic like high-density polyethylene or polypropylene. The interior was pretty snazzy too. Definitely a commute 2-seater vehicle but I'd be weary to drive over the windy bridges here in the bay area with that thing.

I really like the later models as the older one I saw was still in it's preliminary stages.
