One must think to them self about how many people own sports cars, and then how many of them actually drive them in the winter. Just because you may see one or two of them doesn't mean every owner or a majority of owners do. I don't disagree there are people out there driving them around, I'm saying it isn't the norm. I can not recall ever seen a Corvette on the road during a snow storm. The only RWD sports cars I see out and about in the snow are Firebirds and Mustangs, driven by younger people who do not have the money to buy something else. My best friend has a 99 Firebird Formula, he puts winter tires on it and still says it's a handful to drive in the snow.
4 inches of snow is nothing, no one closes school or businesses for that around here. I had class when we got a 7 inch snow fall one morning. If my low-ish Blazer had a problem I would have to imagine a lower and more powerful sports car would have even more issues then I was having.
So, obviously, things are a bit different where you live. They dont' allow chains around here because it don't snow as much. It ices really bad, though, and that's a difference.
People do tend to drive around in their 'vettes a bit more around here. I see enough of them daily to verify this. I also see quite a few on dealer lots, so they must be moving them. I guess.
Okay, perhaps they dont drive 'em EVERY day, but most days, they do. on bad days, they drive the wife (or husband's) SUV.
The GT-R has an AWD system, and an engine in the nose of the car (less weight swinging around the back, though, to be fair, Porsche's done an incredible job with the 911) and I'd rather have a GT-R if it began to freezing-rain while I was at work than a Z06 or a Carrera S. I understand that a car becomes irrelivant in deep snow, especially a sports car. Around here, that's snowplow pickup territory: remember, chains not allowed. I'm sure that's beyond your comprehension, northener, but, hey, I'm down south. this is my view.
The further south you go, the more often a sports car gets used as a daily. I'm sure some Hollywooders drive their Ferraris year-round. 'cuz they can.
So many GT-R owners will drive their cars as dailies, and they may be (slightly) more popular in the north thanks to their AWD and engine layout. However, the deep snowbelt is a different story, as you've said, and your 60,000 dollars might as well be spent on a Ford F-450 Power Stroke with all the trimmings. and a Plow.
Hey, Might as well make some side-money, eh?
Oh, you guys, I'll bet, Have much more aggressive snowplows than we do down here. Probably those snowblowers.
