the nsx is probably the best car i ever had on icy roads. So, with proper snow tires and a normal ride height, it should be nice to drive in this kind of weather.
The problem is, that, at least in my area, there's probably half of the car without right equipment (summer tires, rwd without LSD, worn all season tire, bad wind shield wipers), 80% of idiot who doesn't know how to drive, over-confident dudes with SUV/Jeep that thinks himself as god walking on water.
The chances of yourself being slammed by someone is very very likely. In that regard, it's not proper to take the nsx out, even if I have enough money to buy an used nsx and not cared about the cosmetics things.
