I ordered my 2013 M5 last week and I've been given a build week of late 28 or early 29. Will not know the exact week until first of next week.
Here's my specs:
Moonstone Metallic
Black Full Merino Leather
Dark Red Sycamore Wood trim
Driver Assistance Package
Executive Package
20" M light ally wheels Style 343M
Bang & Olufsen Sound System
BMW Apple iPhone Media/ BMW Apps Version Snap in Adapters
Now it's the waiting game. I'm hoping for a delivery the second or third week of October which is a 13, 14 week lead time.
Of course I'll check the tracking daily and update my post accordingly.
