Found on another site, obviously Corvette based. My first thought was the SV 9 Competizione, but after looking it does not appear to be.
it's not a C12 - C16, those only have 2 taillights... I think it's a small company otherwise Gunman would have gotten it himself.
All that can be found is this: http://snap.ultimative.org/2014/chevrolet-c2-corvette/ AUthor seems to think Fairlady Z rebody due to different dimensions. Its no tuner that I know of.
Thanks Innotech, I figured if anyone knew, it would be you <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/smile.gif"></A>
He also thinks it's more likely a vette. Exhaust placement looks like the 2 pipe vettes I've seen. But I swear I've seen that car on this site before.
There are elements into tricking you thinking it's a C5, but the door mirror is in the wrong place, no strake down the door and just some of the general fitment of panels makes me think it's a rebody/kit car.
