If your supplier says:

That motor's 7 years old.
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Parts at central warehouse, you'll get them next month.
We don't make parts for those.
We only do warranty work.
Our techs only fix late models.
No clue what's wrong! So we'll work time & material.

Baloney!!
