To the OP. For sure get the SportLine for the seats and the DHP for both of your needs. The DHP really give you the best of all worlds, including a way to customize your setup. For example when I get my car I will probably always keep it on sport but in the I-drive i am going to configure the suspension to comfort. So you get the sharp steering and response without the stiffer ride. You can do that only if you have the DHP. Also since your configuration is very similar to mine (minus the premium package) see if the 335i is not something you like more. The price difference between the two is not great when you add the lighting package and moonroof to the 328i. just a thought.
But definetly the DHP is a must.

They created the Lemon law because of this SUV. If I didn't know better I would have thought my wife had a thing with the BMW service manager.
