Even though the Ferrari cost more then the Lambo, I think it is a better competitor then the Mclaren F1 vs. the Diablo GT. I am a Ferrari fan, but the Diablo GT is awsome. I would pick it over the F50 GT as well as the Mclaren F1. OK because "Lamborghini"(below) thinks this is a dumb comparison, let me rewrite the question. If you were at a track and I had a Diablo GT and a F50 GT witch would you rather take for a spin?
