You may use expression properties:
The following expression below means: the item is shown if, the same value is checked in the {car} question and it is not selected in the {bestcar} question.
{car} contains {item} and {item}!= {bestcar}
Every ItemValue object has its own visibleIf property. You may override the top level choicesVisibleIf property and define visibleIf expression for an individual choice item.
