Sitting over the winter really isn't too hard on an A. You may get some temporary flat spots on the tires from sitting.
The hardest thing on them is to start them up and not allow the engine to get good and hot in order to evaporate the moisture/condensation inside the engine. If you are just pulling it out to start it up put some cardboard over the radiator to help it get up to operating temperature.
Stay with the car so you don't overheat it with the cardboard covering the radiator.
