Agree that there is a very slim chance of finding very old stocks (1 year or longer) of a brand new model especially if the specific model is still selling significant number of units.

Kindly correct me if I am mistaken:

Don't remember where I read or learned this but although you might save on the purchase price, it might have long term implications on your ownership cost. First is the oil and other fluids, if these are left unchanged beyond its optimum life, it could be bad to your car. Another thing are the movable parts which should be moving and may have accumulated rust. Third is the paint, the old unit might have been stored under the sun. By the way this could also be bad to your interior especially the dashboard which may become brittle or deformed. Better also check the condition of the wheels/rubber as they may have been deformed.
