I was raised in an era where Lamborghinis had wings (Countach and Diablo). Murcielagos look great without wings, but for some reason the car seems more complete to me with a wing on it. This wing fits the Murcielago perfectly.
There was another company out there with a grey Murcielago LP640 that had a wing designed by them. I think it was EDO Competition. That car stole my heart and turned me onto Murcielagos when I thought the Diablo was by far one of the best looking Lambos ever, second only to the Muira.
