TBH, I'm all for "specific-purpose" models (X7) but not a fan of "in-between" models (X4? and X6). I always thought the X5 was already big (maybe even too big?) But I didn't know there was a market or growing demand for something even bigger so I agree with BMW if they choose to go that route - worse thing is if they miss the opportunity and lose out to their competitors.
All this talk about bringing in new models/series is overwhelming on paper, I just want to see when they're finally available and see the reception of them (looking specifically at the 2 and 4-Series).
