The whole clue is the definition (& lit or double definition).
How the clue works
The whole clue is a cryptic definition: The opera for petrolheads? gives you CARMEN, the famous Bizet opera, but split it into "car men" and you've got blokes mad about motors — petrolheads, in other words. That question mark is your nudge that something cheeky is going on with the double reading.
