If you are going to leave your car for a long while put it away when it is at working temperature. Make sure that the battery is disconnected and the fuel shut off. Chock the wheels and leave the parking brake off. While the car is not being used keep the battery charged and, if possible move it backwards and forwards a bit regularly so the tyres don't deform. If you have a starting handle it's worth turning the engine over every now and then. Many people would drain the fuel but I don't as I have never experienced problems starting an engine that has been standing for several months with the 'old' fuel left in the tank. A cool dry environment is much better than a warm damp one for the bodywork.
