I don't think you really made a point, we all knew about the retractable hardtop but when a car has a retractable roof it needs to be built to handle the road while the top is down. Besides the specs of a Murcielago is better than the Carrera GT anyway so I don't even know why this is being disputed. And read up, the built numerous engines for Lotus teams. Lambo even built engines for boat racers. Trust me I wouldn't post a rumour.
