It's been 15 years since McLaren released its last GT racecar; the infamous McLaren F1, which is, quite frankly, the most fantastic racecar ever created by mindkind. The McLaren F1 won the 24 Hours of Le Mans on its debut and won many races after that.
That was all 15 years ago though. Thankfully, McLaren has released their plans to turn their current production road car, the MP4-12C into a limited production GT3 car.
