how bad is winter for an old car?

When I put mine away and I'm sure a lot of other members do to for the winter,I put it up on jackstands,remove the battery,make sure the tank is relatively full ,with some fuel stabilizer in it(Stabil),check the anti freeze,I need to -50* to be real safe. I think your car should be fine.8)
