X5 Facts:
Jan : X3 made appx 13k ; X5 made appx 11K
Feb X3 production 12,892: X5 made 12,200
I would think that increasing production of X5's is a better indicator of success/failure of X5 than focusing solely US sales. Also, the X5 commands a much higher price outside NA. Now price is also affected by taxes. Bottom line is production volumes are increasing. Of course, it would be safe to assume that generally production equates to sales.
