Rant about forsale cars and rust

On all of the cars that i have bought over the years, the rust was free and i had to pay for the rest of what's left!
There's no such thing as rust free, even on new vehicles, anything that is steel and uncoated will have rust on it in 24 hrs or less. (flash rust)
I think it's a term used for no rust through anywhere on the body, that's what i call rust free.
I've seen cars that were VERY rotten and that ain't a pretty sight! I even still have a few that i use for parts and it's amazing how easily some parts come off even with the heads of the bolts half gone!...... Go figure.
