Does brands like porsche need to produces cars like panamera??

Its a funny thing to say that a ferrari had just produced a 5-meter long, monsterous 4 door saloon, but reality prooves that more and more sporty brands are having their good times designing bulky and big saloons, like the porsche panamera, besides its monsterous power, which most of the other porsches have, the panamera is utterly unsightful and I do not find a single thing on panamera to make me to take my views off a mercedes-s class. First we will talk about the looks, so ok the porsches have a similar design amongst themselves to make them more "porsche". Well this design in my opinion is classic and elegant, but since the panamera is nearly 5-meters long, 2 meters wide and has a body-weight of 2 tons, the design looks more like an estate than saloon, it also looks bulky. And most important of all, I doubt if any millionaires will like to sit in a car without a BUTT (oops boot) i mean, the panamera looks so estate-like that the car doesn't look like an expensive, exquisite saloon, rather than a big family car. Performance wise, I would agree that porsche makes excellent engines, but I also doubt if the rich men would be sitting in a car, chatting with his friend, with a noisy engine infront. If I am a millioinaire, I would rather buy an mercedes benz s class with a boxster, the latter is only slight more expensive but with a lot of fun, whereas the panamera do seems like a fat man trying to be agile. I would like to end this speech with a question, porsche, are you ready to take the mercedes head on or not?
