I saw something about this on tv not too long ago. Pretty cool looking. I probably would have given it more power than just 10 over the Merc. I think the coolest Lambo ever was the Diablo VTTT. Only 8 were built, stock power was 752hp, but the stage 2 option was 854hp with two turbos, pushing the car from 0-60 in 2.9 seconds. Lambo ran the Diablo GT in the LaMans Series a few years ago, but thats about it in terms of racing heritage, except for the countryside races in Italy and Europe back in the 60s.
I think the coolest European supercar right now is the Maserati MC 12XX. 800hp/780tq, 0-60 in 3.2, 0-180 in 19 flat, and a top speed of 242mph
