Not all RWD cars are that bad in winter time.. atleast here many people buys RWD cars just for winter to have fun whit. I personaly haven't driven one in winter time, so can't say would it be worse than driving a FWD car. I was just thinking, can it take cold (-20C - -30C that's around -4F - -22F) and still work normaly.
Not going to boost any more out of it. So looking info about stock consumption what nissan has told in the specs.
Too bad GTR is way too expensive (double the price of gts type m) and has too big engine (insurances and vechile taxes raises) and use too much gas for me. And haven't found any GTS-4's imported to Finland..

so it's 2l gts type m (or 2,5.. but I'm fine whit the 2L version) or then have to look some other interesting car.
