I have.a G12 7 as well. When it’s icy all seasons don’t cut it. I would recommend winter tires. Tire Rack website has some pretty good deals.

You bought it at retail price from a dealer. There is probably a 10-15k difference between trade in and retail. It’s still worth the same amount at retail. You could still sell it for around what you paid if you go private party. Enjoy the car.
