Sam joins Leo to talk about storing cars for long periods. If you have to park your car, there are some things to do to protect them. First, get a car cover. This will at least protect a car from caked-on dust and dirt from long term storage. At the very least, you can get a roll of plastic wrap and wrap it up. If it's not going to move for longer than a few months, the best thing to do is fill it up to the top. That will minimize air and prevent fuel oxidation. There are also additives you can add to preserve the fuel. Sam also recommends starting the car once a week and let it run for a while. Keep the tire pressure up, and even drive it around the block once so that you're not on the same spot on the tire.
You'll also want to check under the hood from time to time to be sure that no nests or critters are chewing on the wires. And either remove the battery or put a "trickle" charger on it to keep it functional.
