I'm torn on whether I want to go xDrive on my 340i order. I've got plenty of years driving rwd cars in Chicago winter with winter tires on, but I do like the simplicity of an AWD car + all seasons instead. Less hassle winter time, less expense (no need for an extra $1500 set of wheels/tires), etc.

All that said, I care about the driving characteristics of the car the most. Has anyone driven them side by side? Assuming msport 6sp for both, are there noticeable performance penalties on the xDrive? There typically are through higher drivetrain loss and added weight...
