The objective of a luxury brand is not volume sales.
There is the well known anecdote of somebody asking André Heiniger, then chairman/president of Rolex: "How is the watch business?" and he answering something along the lines of: "I have no idea. Rolex is not in the watch business..."
Wild assertion. Ferrari is currently #8 largest market cap for a car manufacturer. They're valued above Mercedes, BMW, Volkswagen and every other Euro car brand.
They couldn't be more successful as a small automaker if they tried. But you think they need to do something like this to drive attention and sales?
