Wow ... like Apple sticking to making personal computers, yeah?
Or Lamborghini making tractors for that matter ... or BMW making aeroplanes for the Nazis.
Look, if you want a RWD and a BMW, guess what - you can buy one! But the difference is that other people ... you know, the rest of the world, who want a different type of car ... now have a BMW to chose from. BMW sells more cars. Win.
I really don't get this assumption (and it really is nothing more than an assumption) that somehow BMW is incapable of making more than a sports sedan without "diluting the gene pool" somehow. That's cack. they're a massive company who know what they're doing.
