I've also heard that it's a fantastic experience, which is why I'm waiting to do it.

And waiting... I requested PCD ("Performance Center Delivery") back when I placed my order on 2/20. My X5 finished production on 4/9, but the earliest date I could get for the PCD is the week after Memorial Day. According to the person who does the scheduling in Spartanburg, they normally try to arrange the PCD for three weeks after the vehicle is finished, but right now they're very backed up due to demand. So if you're interested, make absolutely sure you get your request in when you place your order, and be prepared for a bit of a wait.
