Thank goodness Japan has a wild side. Interspersed among boatloads of politically correct Toyota Priuses comes the occasional Lexus F hot rod. And over at Nissan, punctuating the truckloads of morbidly thrifted Versas is the random GT-R. The muscular Nissan has a legacy going back decades, but for the most part, this fast and furious coupe boldly goes its own way. Quirky, jerky, and perky, it has so much personality that J.D. Power wouldn’t know how to score it. It’s a riot of sensation and sound—some annoying and others cyborg cool. On one hand, it’s a bargain supercar for hard-core gearheads. On the other, for a coupe from a nonpremium brand, the GT-R is a bit spendy, as it costs twice as much as a Chevy Camaro ZL1.
