My C8, goes to bed for winter, when the temps, stay below freezing. So the first snow, that does not melt away. I used to drive my cars year round, with 4 season tires and never had any problems. Then Quebec, forced us to winter tires by law, so I did till 2010. Then a friend of mine said , you get at least 5000$ more on trade ins, now more, when you do not take it out in winter. He was right. I used to trade my cars, every 2 to 3 years , so it was worth it. Savings on tires , insurance , registration etc. We have a car that goes year round , so why mess up my C8 bunny! Another reason, is I love change, and change costs a lot, so this way, every spring, it is like I have a new vehicle in spring because I have been driving a Volt for 5 months!!! Going from a Volt, to a sports car, is like going from winter to summer weather, in an instant.
