By adding "parts" to the submission title, at least we're still talking about a subset of the car.

Can't say the same for "rumor."

That depends on whether the rumor is a subset of the truth. Sometimes true, sometimes not.

Truth: Joe Smith has never beaten his wife.

Rumor: Joe Smith no longer beats his wife.

There's some truth in the rumor, but no rumor in the truth.
