I just changed the oil in my 99' 328is today and I was suprised how easy it was. Had to go to auto zone and buy the 36mm socket but other than that it was a snap! What made it easy was the link attached to this post. If you guys haven't checked this out yet then just take a minute to look. I figured it would be good for the newbies because it has topics for general fixes and things of that nature.
