    The brakes rust up from not being used.

    The oil in the motor doesn't get circulated to coat the metal surfaces.

    The transmission ATF stays in the transmission pan and isn't pumped through all the passageways or through the clutch packs.

    The tires get flat spotted from sitting on them in one position for months.

    The gasoline in the tank gets old.

    You will almost always have issues if a car sits for a long time - especially if the car is already older.

    If you have to leave a car for an extended period, there are procedures for doing it properly - fuel stabilizers, battery tenders, properly raising the car up to prevent the tires from developing flat spots up, greasing rust-prone parts, etc. - and then when the car is put back into service there will be things that need to be done first to prevent damage. Changing fluids, pulling the spark plug wires off and allowing the engine to crank without starting to lubricate everything, etc.

    The best bet (if possible) is to simply make time to take the car for a quick drive on a regular basis.

    It’s more likely to cause long term problems with leaky seals gaskets etc but you may get lucky and not have any problems

    A car will have certain things deteriorate when sitting. Tires for one, belts & battery. Cars are designed to run.

    No truth in that.

    "Moving parts" SHOULD be allowed to move once in a while to maintain lubrication and prevent corrosion. Gasoline goes "stale" after sitting exposed to air for extended periods and certain volatile chemicals evaporate, leaving a varnish like substance behind to gum up the carburetor or fuel injectors.

    Break down?, no they deteriorate. Rubber seals and gaskets dry and crack. This causes leaks.

    It is inaccurate as stated, but not entirely false.

    Various parts tend to deteriorate if neglected for long periods of time.

    That isn't the same as breaking down.

    No, but the braking system can eventually get stuck due to rust. It should be driven once a month or so.
