flypaper, when Yugo went away do you think they continued to make parts?
If a company is out of business and money, how are they going to make parts?

When the creditors confiscate machinery in lew of money owed, how can a company make parts. This is just an impossible situation.

IF this was true, why only cars? Why not legislation for my old microwave, TV, computer ect.

I'm old, I heard this stuff 55 years ago. I didn't believe then either.

If you can show me actual law, well then.......but I wouldn't look for it, it is just not possible.

A lot of car makers went out in the fifties. Aftermarket manufactures kept parts flowing only as long as they made money. After that, it was done. Buyer beware.
