Top Gear filmed a segment on one, not sure when it will air.
They are making one a day and customers are already receiving them.
Killer car.
McLaren also is coming out with a "P13", priced around $200k it is supposed to compete against the 911 Turbo. Comes with the same engine in the 12C but detuned to around 450bhp or so and much lighter, should be interesting.
