This thread is going to be so hateful.
I know. I don't get the hate for the X6. Like it is an offense to some simply because it is not practical in terms of cargo carrying and rear passenger accommodations.
I's take the X6 over 5 Series GT or X4 over 335 GT anyday.
Probably because all of these represent vehicles that nobody ever asked for. Take a practical wagon and replace it with a GT, then does it perform like a car-based coupe? The 5GT was heavier and more cumbersome and poorer handling than the Touring, so what was the buy-in - styling only (and the sales numbers show how well that one sold). That said, I've got no idea how the sales of the X6 have been. For the X4, the answer lies in the performance numbers between a 4 series coupe, a 3 series Touring, a 335GT and the X4 - see which one wins. BMW extolls itself as a "performance" luxury manufacturer, and in my mind, loses credibility with these models (along with poor durable quality reports).
Did anybody ask for the CLS? Mercedes took a chance and it paid off. BMW will take chances for those kinds of successes as well.
Sometimes it's not about what people ask for (people ask for the dumbest things - think The Homer), it's throwing something out there and seeing if they buy it... these are not vehicles of necessity, so it's competing with SLKs and CLAs and Evoque Coupes, 300 SRTs, FJ Cruisers, Nissan Jukes, Harleys, etc..
it's a vehicle you buy in order to say, "I don't need a minivan or to save money, I can do whatever I want!"
