MX-5 NB as a daily and winter vehicle?

Moin, I’m short: I’m currently playing with the idea of getting myself a MX-5 NB as a daily and winter car. What’s your opinion about this, especially about rust? Some of my friends drive the NA and the NB as a summer car, some have registered it all year round, but rather as a fun car in rainy weather. As a passenger, I always loved the driving feeling and visually I also find the things quite great. My question is whether it is still worth an NB In the north I rarely have snow, but salt and cold are still a bit worried about it. Will the longitudinal beams rust away immediately or can you seal them reasonably? I don’t want to take away the individual pieces with good longitudinal beams, just so that they start to crunch after a winter What do you think about it? What would you recommend?
