answer:I’ve left cars sitting for longer and had them start up without difficulty. Two months isn’t terribly long. I would fill the gas tank since an empty one will collect more condensation out of the air unless the space where moist air would be is filled with something else, preferably gas. The oil should be fine for that period of time, but the tires should probably be filled. The only possible concern I can think of is the battery, but if it is relatively new and your charging system is still in good working order, it should still be able to fire up on the first try in a couple of months. Hell, I left an old beater VW in the corner of the yard neglected for five months and it fired up on the first try.
