Do you all just like switch off all critical thinking when making these type of posts? I mean seriously. Pay real good attention here. The discussion was about who is more successful, i.e. able to command a higher price at the top end, not who sold the most luxury vehicles. BMW sells more luxury vehicles overall we know this by their blazing sales numbers profitability. That Mercedes moves more cars or gets higher prices at the top end doesn't mean they're automatically going to be more profitable. Profitability comes from a myriad of things not just who sells the most expensive cars. Clearly BMW is a more efficiently run business than Mercedes is right now, but again that was not the point being made or argued here. Prestige in the market, and how to measure it, is how this discussion got started. Two things can be true at once.
