Why does Dodge go cheap with their steel?

poorly recycled steel is usually a bargain...and still contains contaminants including oxygen.When finances are stressed companies are forced to buy cheap steel and parts...and your new truck will fail mechanically and rust from the inside out no matter how much paint or undercoating is used.This can be year specific depending the companies' financial health.We all have seen certain years including those early 70's chevys' that just rusted out in 2 or 3 years.That's why it's imperative to buy a mint 3 or 4 year old truck and know your good...or take your chances.
A lot of the late Dodges will be scrapped in 7 or 8 years
