Greetings to all members. I'm a newcomer of this club and I'm waiting for my E90 323i to be delivered in 4 weeks time. I have waited for 2.5 months now for this new baby that comes with:Xenon headlamps (without adaptive)Active SteeringComfort Access162 RimsiPod interface kit (retro fitted by BMW when arrives)Mud flaps (retro fitted by BMW when arrives)Tail pipe (retro fitted by BMW when arrives)Sprint Booster (depends on the performance)I have a few questions that needed some expert advise.1. What is the difference between 323i engine and the 325i engine? I know it is detuned 2.5L but what are the fact sheets and why create another series, etc.2. Though I have specified comfort access in my option list, I have not seen the comfort access in action for BMW but it works well in the CLK. How does it work in terms of first entry to the car? Does the interior lights up automatically when it detects the key and beeps pleasantly, etc?3. Has anyone tried active steering and is it a nice to have or forsee to be a standard for all cars?4. Has anyone installed the BMW standard iPod interface kit and can the radio displays the title?5. Has anyone used a Sprint Booster on the E90 before? If so, is it necessary to have it?Thanks in advance guys.
