These are the two hottest mid engined high production supercars right now. I'd take the mclaren, it would be tough because I love the italia too but my love for the mclaren brand would sway my decision. It's amazing though, both are amazing cars hailing from the two most successful racing teams of the past few decades. The pedigree of these two beasts is exemplary. I love them both, extreme performance and while they are expensive, ten years ago you had to pay wayyyyy more for what you get out of these cars. Its just astounding how far the automotive industry has come in the past twenty years, in performance and design. I love the supercars of the early nineties, the mclaren f1, the f50, xj220, eb110, etc. are some of my favorite cars but so much has changed. You rarely even seen a Ferrari with a third pedal anymore! It's crazy !!
