Nissan has announced a new limited-production Nissan GT-R Spec V model which we’re still having trouble wrapping our collective brain cells around. The GT-R was unveiled at the Tokyo Motor Show in 2007, and it has taken all before it since then - it is a technological masterpiece that looks like a relatively normal car, but outperforms cars worth double, triple and more. In Japan it sells for 8.6 million yen, translating into the cheapest production supercar the world has yet seen. Now, the Spec V is being shown at Geneva and has already gone on sale in Japan for 15,750,000 yen (JPY) – an increase of 83% in price – and the engine produces NO more horsepower. So what do you get for an extra US$72,000?
