Apparently build by Sbarro in Pontarlier France (essperra barro)
I have been in their museum in pontarlier once while my sister lived there, they had some really crazy stuff standing around including a midengined metro (not 6R4) with a jag V12 engine etc etc.
lots of strange things nothing really beautifull though.
There was a story floating around the net, that Sbarro had taken up a contract to restore a custumours wrecked LolaT70 and that they've eventually replaced it with a replica they build themselves (students in the Sbarro college), having sold the original car for proffit. without the custumour not knowing this,
I don't know wheter this is true, but if it's this one I wouldn't want it for the story alone.
