Thanks for the updates. I've got mine on order now - 520dSE auto Touring, also with professional nav and one or two other bits and pieces - though probably not quite as highly specced as yours, MacTech. Should be with me early-mid December. For my current driving (180 miles round trip to work about 3-4 times a week, nearly all of it derestricted dual carriageway or motorway) the BM should be just about ideal. Certainly looking forward to a step up in economy!
Still looking for a buyer for the S211!
