I haven’t heard the “selling body parts” canard before, but in the Middle Ages there was the infamous blood libel, where Jews were accused of killing Christian children and using their blood to make matzohs and other holiday foods. This sounds like a modern version of the same accusation.

Just out of curiosity, do those abortionists who "want a Lamborghini" happen to be Jewish?

If so it might account for the phrase.

Otherwise, "body parts" sounds like what the Red Chinese do to Falun Gong.

It’s been used since at least the 1930s
