As with any car that doesn't get driven many miles @ year, you should cut the normal service schedule in half. Also keep the tires a few pounds overinflated. Any rubber componets can fail over time so have the car inspected "under chassis" whenever the oil is changed !! You have a Great car so have fun with it.
