You'll have a blast if you pick it up in SC, those memories will last a lifetime. The ability to track an X5 and go thru the offroad trail is a lot of fun. The entire experience is first class and I am planning to it everytime I buy a new BMW.
BTW not sure if its been mentioned on this board or not, but for other BMWs, both ED AND PCD delivery are now available. Not only can you pay less for your car, but you can ride the autobahn, test yourself at Nurburgring, and have all the fun in SC! Unfortunately BMW was a couple of months to late for me
