Also remember, if the car is not going to be moved, then park it with the wheels chocked and the handbrake OFF. Brake drums can seize almost immovably solid in winter after standing unused for as little as about 10 days, so keep the handbrake off. However, if you have the facility on the drive or in the road where you won't get nicked for driving uninsured/no tax etc, once the car is started up, just drive it backwards and forwards a few yards and apply the brakes, including the handbrake, This will help to keep the cables and pivot links lubricated and free, and also wipe any rust off the brake surfaces before it gets too heavy and causes pitting. For the handbrake, pull it on to its fullest travel, on and off a few times, again just to keep things moving freely.
Any car lasts longest when it is regularly used, and when air circulates around it to dry out condensation and dampness. The nearest you can simulate that during the storage period the better. Even opening the car up for just ten minutes once a week is better than leaving it open a whole day but only once a month.
