They should be able to get it to you for Friday, Saturday at the latest I would have thought! Mine was taken down from Trone to the dealers on a trailer, arriving on the Friday. I was able to pick it up on the Saturday. Keep hasling them...
As for Sunday, yep, all set and really looking forward to it.
It's arrived, e93 M3 Convertible: M-DCT, JzB / extended BB, and most of the options.
