I thought about an E70 X5M when I got my F15 50i...since they were close in price. The main reason I went with the newer car is because of the better technology with Driver Assistance and Safety. Also, after reading here a lot I would not get the 50i/X5M engine without a warranty.
I prefer the exterior of the E70 but the interior is much better in the F15 to me.
