I never liked any of the so-called 4 door coupes, Cls, Rs7, besides 6 serious gran coupe. Even more so on the panamera, X4, GLE. But X6M is the only one I think it looks cool, and I don't even like the standard X6. I have had many cars (100+), and very picky on the cars I buy, but I find it I like my X6 M more and more
