A new-ish, well-maintained vehicle with new tires, fresh oil change etc, if it's left dormant & undriven untouched in a residential driveway for 1 year, will it be driveable after 1 yr?

I know it isnt the question you asked but the easiest way around this is to find someone you trust who can just use it sparingly, preferably someone with a garage who can keep it out of the weather for you.
