I don't know what I'd take, but they're all amazing machines! I'd probably go for either the CGT or the 918 simply because I prefer mid-engine over rear engine. I'm not sure I'd like a hybrid car and I do like a V10 - I find V10s to be very sonorous and emotional, so maybe the CGT? Either way, if you were offering any three of these as a gift, I wouldn't refuse! I even like the idea of the XJ220. That's one big impressive cat! Meow! Although 6 cylinders is a little low of a count.
