Both are great within their own right. Dunno if I could pick one. The raw sound of the F1 or the engineering feat of the Veyron. Before this video it would have been Veyron all the way because of the engineering. I loved the F1 when I was a kid, but never really understood it properly until now.
All I do know for sure is that I love the La Ferrari lol. Then these two and then a load of other cars.
