Ah, the Enzo, it's such a magnificent slice of automotive gem. Fun fact; I've learned that the model name isn't "Ferrari Enzo Ferrari", or "Ferrari Enzo" as loads of people call it, but just "Enzo Ferrari". I thought that it was a fun piece of trivia, though I'd personally take the Maserati MC12 over the Enzo, just slightly.
It might be mostly based on the Enzo, but Maserati's engineers have somehow made it even better, with more downforce and with lower drag. I'd also argue that the bodywork is much prettier :-O
