Appreciated, however what I am looking for is a response as to the differences between the 123N and the 123O models of the F30. From what I understand, the 123O may have a different engine -- the N26 which is a SULEV variation of the N20. What does that mean? Does it affect performance? Reliability?

Thanks.
