Hey Yazza, wake up, this is 2003, and the Diablo is quite obviously out of production. Apparently when you said "a few months ago", it was more like "a few years ago". The only cars Lamborghini is currently making are the Murcielago and Gallardo. And it doesn't matter wether a car is out of production or still in production as long as it is considered as a production car. And Farbod, the Bugatti has not been officially tested. This is why you will find many different claims on different sites. You guys should hold in your claims that the Veyron is the fastest production car until it actually IS a production car, which will be delayed for around a year. McLaren F1 still holds the title!
