I found this site 2 years ago and i found it very interesting, so if you want this is the link to the main page (the guy talks also about his other stuff, motorbikes, a mini...he had also some Elises, BMWs, a new M5 but he sold them..)
He seems to be very serious (and had a lot of money for his projects ), he is building his own racing car with a hayabusa engine, all wheel drive, superlight contruction...he have been doing this project more than 4 years and now is near to completion of the first prototype. He also plans to build more and sell them.
the DP1 page link is in the main page, the 5th icon (the black small car) in the menu from the top.
I've tried to find in the forum but I din't find anything, so I think it isn't a repost, if so excuse me.
