I agree with your choice of the M Sport package. I did not order Active Cruise but i did order HUD and Damper Control which is a separate option. The Damper control let's you change the shock absorber settings - that is something that really changes how the car feels and drives. I would consider Active Cruise over HUD if your commuting that much. If you use the 407, I think it's less of an issue.
