Reader beware - the following may be considered very offensive to some NSX owners!
Cars are meant to be driven. NSX's are cars. Therefore, NSX's are meant to be driven....in the rain, snow, ice and sun! Mine gets driven in all conditions, 12 months a year - even when I lived in Indiana. I even drove it from Indiana to my new home in Charlotte, NC in January during a snow and ice storm. It got really hairy driving through the mountains of Virginia and West Virginia with a thick layer of ice on the road. I nearly lost it several times, but finally arrived in Charlotte at 5:30 in the morning. It's a daily driver with over 100K hard miles on it. It looks like crap, but man is it fun to drive....all of the time. I can't imagine owning it and not driving it all the time. I have another car, but given the choice between a Jeep Cherokee and my NSX, the NSX wins out almost every time. Most people will probably disagree with my philosophy, but I just thought I'd throw it out there. Happy motoring.
