Opinions on N42

[Big H]

Looking to pickup a touring for the lady - and not really familiar with the N42 (looking specifically at late model E46s)
Had an M43 for a while which I found quite slow but otherwise OK - what's the verdict on this one?

Junk - hold out for a 6 cylinder 325i/330i M Sport touring - may be more expensive up front but you'll be thankful down the line.....
