i'm loking at these 2 bimmers and would like to know where I can find out about the differences between the two models...any suggestions unless any of you can give me the info...thanks!

First thing I know is the wheels are differnt...i know its a bigger engine but I don't know by how much.

Well, I would think the biggest difference would be that ones a 2.3L and the other is a 2.8L. ;)

323Ci Information:

323CI has a 2.5L engine...and 325CI has a 2.5 engine... the horsepower and torque on the 325 is higher by 25..in both. I believe that the sport package is a little different (interior - steering wheel functions) on the 325ci then on the 323ci. Other than that.. really nothing much. Good luck.
