The labels in the "super" call need to match the parameters and parent labels, and the class was missing a closing brace.

Brace matching is easier to spot if you consistently use indentation to indicate nesting level.

    // labels need to match
    super.init(withDoors: numberOfDoors, andWheels: numberOfWheels)
  }
}   // closing brace was missing
