Edward, you should just pick up a good used condition car with good paint and body... drive this one once a month to keep it running and only use the old car in the winter...
A newer car will be safer, usually true, and can get better fuel economy with similar or better performance. Pick up something that has a history of good engineering without a lot of blackeyes for that model developing trouble as they age. If you buy one that went through a restyling recently often it drives down the used car price some on the older body style.
Then it is a matter of working with your insurance agent to take theinsurance off theroad during the seasons where you drive the winter beater. Keeping the newer car out of the salt, sand, cinders and other winter corrosion. Don't park either car on a grass, otherwise the moisture from the ground just gets sucked up under the car creating a great rust breeding ground.
