Why? Who is this for? It's basically a fastback X5 and considering there is precious little space in the back of the X5 as it is, how could reducing it further make it more appealing? Was BMW so jealous of the success of the Pontiac Aztec that they decided to make their own version? Or perhaps it was the timeless design of the AMC Eagle that inspired them. I suppose every manufacturer has their Edsel. This will be BMWs.
