Mine was in the driveway and done being driven end of October or early November, then covered and put away by the 10th or so.
I <3 this car. lol It’s DEFINITELY an obsession, I tried to buy the car away from my mom’s boyfriend almost daily for about 3 years. I can see driving it in the winter when it hasn’t snowed in a while… but covering it and uncovering it is a pain in the ass for me to do by myself, so instead of asking someone to help me do that 10 times over the winter, I put her away. 
Besides, it’s got no heat and it’s a rag top… can you say COLD?! lol
