 We bought our 328i used with 44K miles 
after having it checked out by BMW 
shop.  The driving experience is 
beautiful with all the power I think is 
necessary.  The automatic is flawless 
in it smoothness.  The engine begs to 
be driven.  The greatest drawback to 
this car is the repair bills which seem 
to happen far too often.  Parts are not 
cheap!!!!!  Do not buy this model or 
brand of car unless you can get a 
warranty from BMW.  $1500 worth of 
service each year is obscene, 
particularly in the days of Acuras, 
Passats and Lexus.  I will miss the 
driving experiance, but my retirement 
will not, I'm afraid, allow another BMW 
in my life!
