I did the same last night, after several test drive comparing 2013 low mileage (18k miles) non-cpo to the f15.

There definitely is a wow factor when you sit in the new X. But the $16k more i have to add vs. e70 is hard on the pocket.
In the end, wow factor won, so now the waiting is painfull as i wait for PCD schedule.

Mine is Space Gray, black interior, lux pkg, multi-contour seats and HK sound. The only other option i added is backup camera and space saver tire. I read the spare tire can cost as much as $380 from bimmer source i bought after.
