I placed a deposit of £1000 on 7th July 2011 (OK, I admit, after the Top Gear feature finally pushed me into buying!). Whilst arguably just having limbo'd under the bar at the last minute for one of the very last of the UK's allocation of 1Ms, I yesterday got official BMW confirmation that a 1M has been allocated to me and is scheduled for build in Dec 2011 with delivery in Jan 2012. I'll pay another £1000 to spec the car sometime in the next couple of months - I'm thinking black and all the bits and bobs except elec powered seats
