If you leave a 30 year old Buick Lesabre sitting in the front yard for five months because it has a dead battery, then change the battery and turn the key, it will start running, put out a puff of smoke and be totally fine. Or at least this one I use for a backup car seems just fine.
I asked the car dealer for something dependable when I got this car, and dependable is just what I seem to have got.
