Hi guys,I just got a Manual 116i, and there are a few things I'd like to inquire about.1. Performance - what kind of performance mods would you recommend for the car, and what are the prices roughly?2. Can anyone recommend a good upgraded sound system/entertainment system for the car? I don't need a CD changer, but IPOD compatability, better quality sound overall. Approximate prices would be a great help too.Thank you.
