I did ED this past Nov. - Dec. and it was amazing. Like others have said, check out the forum dedicated to ED and be sure to stop by and read the wiki (located at the top of that forum as a sticky), as well.
To see how much you can save (7% off) head over to bmwconfig.com and choose European Delivery from the right drop down after you configure the car.
Lastly, I leave you with two pictures of my X1 during my ED and a link to the thread where I posted my entire private album of photos we took during our ED.
