I expect someone has spent a lot of money with grand ambitions and is wed to the idea of getting it back. Probably unrealistic but if you put your money and a lot of hours into it? Maybe the remains of a couple of cars have been folded together. As you say the V10 seems a fun idea to make a monster Aero to go RS6/M5 baiting on a dry warm day when the traction stands half a chance. I cannot see it going anywhere other than some remaining spares but looking at the state of much of it I doubt many of the parts remains close enough to original to be re-used on other cars.
