Subquery using IN
I don't understand why this isn't selecting the ModelName's?
SELECT ModelName FROM Model INNER JOIN Car ON Model.ModelID = Car.ModelID WHERE Model.ModelID IN (SELECT ModelID FROM Car WHERE StickerPrice > 30000);

You don't need a JOIN here, just the subquery:
SELECT ModelName FROM Model WHERE ModelID IN (SELECT ModelID FROM Car WHERE StickerPrice > 30000);
