What kind of info are you looking for? Great reliable car just like any n52/N51 engine, the 323i has the 2.5 inline 6 instead of the 3.0 inline 6 (like the 330 and 328) no turbos (like the 335). I have 210k kms with zero major issues (still have my original water pump, no oil leaks, etc.)
I could post my vin info if you want to get a better idea of what your looking for.
