This has been bugging me as well.
The owner claims this is a one of a kind hand built creation. Not to say the guy with the Plazma is not being truthful, but the fact is that there was a website selling the kit as the "Laura 3" and the link is now dead, but I recall seeing it. I fixed the link above take a look at that thread.
Furthermore, if the "Plazma" is a one-off then he has painted it several times. In addition to red:
It was also once black:
Before settling on blue...
And he has changed out the interior even more times:
First Red:
Then Black:
Then blue:
Then Gray:
Then a black and tan:
Before settling on the current design...
I'm sorry but this guy's story does not hold up to the observed facts...
there are more than one of these cars in existence.
