Contrast this ludicrous Ferrari FXX K with the Aston Martin Vantage GT12 we showed you earlier today. Yes, vastly different cars, in price and capability—most importantly, the FXX K will never see a road, at least legally. Also, two very different philosophies, and two very different sounds. The GT12 sounds more like a WWII warbird. It’s a snorty,growly thing.
