An impressive and beautiful car, to be sure, and I will never be able to afford one. But I think that such a (mobile) display of wealth is fairly over the top. It's one thing to have wealth and enjoy luxury, but perhaps it's another to rub it in the face of everyone you drive past. I suppose the same can arguably be said about other luxury automobiles as well, so each person judges for himself where the cutoff point is. But the Rolls seems to be well past the point of demarcation. But, yeah, a beautiful car.
One could always buy one as an investment. Jay Leno's McLaren F1 purchased for $800K, last offer he turned down was $11.5M. https://www.cnbc.com/video/2014/08/29/jay-lenos-best-investment.html
