Greetings,we purchased an E90 323i in October last year with a sunroof & 18" rims. We tested it against the 325 and could hardly tell any difference in the power, well not enough to warrant the extra money they wanted for it. We absolutely love the car. Don't get me wrong, I would love a 335i coupe too, but where do you draw the line? So for our budget the car is awesome, with just enough get up and go to be fun to drive.
