I will always buy winter tires for my cars. Why spend so much on a car you only drive for 8 months a year? As long as a snow plow runs through your area, you should be fine.
As for rust, it is up to you if you really want to garage queen your car just to save it from potential rust. How long...
I also moved to "In Production."
I have now ordered 6 brochures in my name and 3 in my wifes name and have gotten ZERO customer cash offers. If we are in production I'm willing to bet it is too late to request those brochures because they take 2-4 weeks to arrive.
I test drove one and it was a ton of fun. Was actually quicker than I expected. it wasn't very comfortable though. I'm only 5'10" and I had to sit way back and the arm rests were useless for me.
