Identical is the key word for me regarding the X3 and X4. Shame..would be nice to see the X4 with at least sportier headlights to differenciate it from the X3. Not to mention that the Base Macan will destroy this car in pretty much every aspect.
Same thing now for the X5 and X6. I loved how sportier the X6 looked over the X5 especially in the front.
