If you don't rust check a vehicle every year here in the North Atlantic Ocean, you will never have to worry about engines, transmissions etc ever wearing out.
EVER !
No your car & or Truck will be a pile of rusting metal flakes on the ground surrounding & covering any engine under support parts that oil leaked out & protected from the corrosion that is unbelievable, until you experience it for yourself.
Our local Governments to make sure the salt in the air has a better chance to rot your vehicle into dust, also spray our roads with Brine water before snowstorms & freezing events , along with massive amounts of rock salt for traction on the icy roads.
For fun, on clear quiet nights ...you can sit out with the drink of your choice & hear the metal corroding in vehicles around the neighbourhood .
