I think the price is a little shy of 100k, so still less then a GT3. I saw it on a piece in "Super 2tuner TV" filmed in California. I's sure some track guys out there have seen some. 1100 lbs. 255hp. 2.0 g's lateral. Not street legal in US but can be in UK. It is interesting to check out, none the less.
