Well this is funny, I have blogging about a similar issue with my seats on a different thread. My Canadian 2011 e 90 purchased 1 year ago was ordered with all options, including executive package. It came with heated seats and power lumbar and side bolsters, but only manual seats. I don't get it. I am in current discussions with my SA since I was told that power sears were not available, but from what I hear I beg to differ.
