This is also an unfair comparison, since it's unclear how inelastic demand is for full size luxury sedans vs mid size luxury sedans. I'd bet that if BMW stopped selling the 1-4 series, a decent chunk of their followers would buy a 5+ series. Likewise, many people buy a Model S because they want a Tesla and would buy a 3 if it were available.
