Sell or Store

Two years is a long time. I'd be tempted to sell it, even though you will suffer a substantial slug of depreciation. Leaving a car to sit unused for two years will adversely affect it, no matter what you do.  But if you do store it and you can have someone drive it regularly, I would simply cover it and leave it. If that's not possible, put it up on blocks and disconnect the battery. The fuel tank shouldn't be left empty but there should be no more than about a quarter of a tank of fuel left in it. Lightly smear some lubricant over the door and boot seals to prevent them from sticking, and cover it to stop dust building up on the paint.
