I ordered a 323i a week or so ago with a production date of 5/19 (hopefully they can move that up a little bit), and I have been thinking of making some changes to the order. I have ordered the car with the 16" Premium package, Xenons, rear fold seat, computer, moonroof, fog lights, and the wood package. It will be Fern Green with Sand leatherette.
I am considering adding the on board navigation system. All of the invoice's I see have a dealer price of $1675 and a sticker of $1800. When I called the dealer he said that on the 323i it stickers for $1950, and will charge me $1750 for it. He mentions that on the 323i there needs additional items to be installed, but I have not found that information anywhere (including on BMW's website which still says it is a $1800 option). I know you need the computer and one of the premium packages, but does anybody what else would cause the navigation system to be higher on the 323i than the 328i?
