I was recently having this conversation with some car friends; I think the Q8 and Cayenne Coupe pull off this crossover coupe trend pretty well. Everything else; it's not for me but hey, manufacturers aren't out there catering to what enthusiasts think is smart or dumb. They're out there to rake in many dollars in profits, and the market has spoken with regards to these designs. People want them; they all sell.
What I do enjoy is when someone goes on about how "the Pontiac Aztek is the ugliest car EVER MADE" because the Internet told them so, and then they go out and buy a GLE Coupe or an X4 xDrive30i...
