Good advice from Jocko, if you make a habit of leaving car for long periods I would leave handbrake off and add redex to fuel to stop things gumming up (when dinosaur juice evaporates it leaves a sticky residue behind which can clog injectors and generally cause problems in fuel system) - I even use it in my lawnmower and it starts easily after winter layup. Personally I would also add some Molyslip to engine oil, as this stays in bearing surfaces when the oil has drained away and will protect them from wear during period when no oil is present during startup.
I would also leave battery connected to a maintenance charger while it is layed up, after more than 10 months standing it will have undoubtedly sulphated up and battery will be permanently damaged, this is even more likely in warmer climate where battery discharges faster. Beware leaving windows open as mice and other things may find it an ideal place to nest, and they will chew up the upholstery, seats and anything else they can get their teeth into (including wiring sometimes).
I even take seat off my motorbike when in garage over winter as the mice will make a home on the nice comfy foam in that, I have had mice in garage a couple of times in the past (cute little brown woodmice with button eyes, not the grey housemouse) and you should have seen the damage they did to books, leather boots, golf bag and some foam I had stored, not a pretty sight.
