Despite the fact that the design study of its all-new P1 supercar is set to debut in Paris next week, McLaren is still keeping busy selling its existing MP4-12C model. We've heard news of other special edition Macs , after seeing the one-off X-1 Concept at Pebble Beach , and now it seems that a limited edition MP4-12C will be made available for the supercar-inclined one-percenters of Singapore.Slated to be delivered this weekend to coincide with the Singapore Grand Prix are three Fire Black SGP Edition McLaren MP4-12Cs. Very little is known about these specially modded Macs, save that they feature a unique paint scheme, matching interior, revised front and rear bumpers and lightweight wheels.According to the rumor-dropper at Teeemspeed, each of the special-edition cars will command a whopping $1.28 million SGD (around $1.04 million U.S.) asking price. Lest you think that price is too steep for even the very capable MP4-12C, note that two of the cars have allegedly been spoken for.
