i'm picking up a 323i coupe for my wife next week, it's auto, metallic, sports seats and suspension, high beam assist and adaptive light, floor mats, 17" v spoke 188 wheels. There's obviously not as much grunt on paper vs the 325i but not major difference while you're driving, esp when you're accelerating (ie 60-80km) while driving.
For the purpose of a wife's car, it has the looks, that's enough. No need for the extra speed. IMO you either get the 323i for the entry model, or go all the way to the top for a 335i or a m3 for the grunt.
