I went through the same trauma - and just picked mine up also.
It's a huge amount of fun to drive, practical, gas mileage isn't totally horrible, and the insurance isn't awful either. The reality is that it's not *that* much more fun than the X6 50i that it replaced, as the roads and traffic in Seattle are so dire.
However, it's so much more fun on the windy roads when you can hit the "M" button... what the hell, do it - you'll be glad you did
