The car has been around forever... it will be painted before it's all said and done, that is just test fitment of the body.
I don't know if they're planning on keeping the same paint job or not, since it's basically a "new" car now they will probably change it. They're running straight alcohol with no intercooler... should be interesting, to say the least. To my knowledge no one has ever built one of these V6s to run on alcohol.
