I don't think this is always clear-cut. Sometimes premium goods have a certain amount of luxury in them to justify the purchase price. A good example is a Mercedes. In most countries, even the base model Mercedes has a high standard level of trim, and luxury features. Yet, in Germany, you can still purchase that vehicle with plain trim and denuded of lots of the luxury features. Most of the taxis are like this. The base German model can be considered a 'premium' product, because it has a higher level of engineering, safety and build quality than other vehicles, but doesn't have the luxury baubles which people like to have to justify the higher purchase price.
