I'm sorry if this topic has been beaten to death already. But anyway I was adding up the invoice prices for both the 323Ci and 328Ci. With both cars including the premium package, the moonroof, leather, in-dash CD, and metallic paint.
Adding everything up, the 328Ci only came up to be about $2000 more than the 323Ci! So basically you are only paying $2K more for the bigger engine and other enhancements of the 328....
