Good manual for maintenance and diy fixes. I have a 2001 325xi wagon... doesn't show much about stuff for the wagon but it seems not much is different from the sedan when it comes to mechanical work. Great visuals for suspension, brake, engine work. If you're like me, you look to bimmerfest.com, bimmerwerkz.com, bimmerforums.com or a similar forum for diy jobs and the advice of fellow owners. This book is a nice reference for when you're on the job (or preparing for the job) and don't have the time to do that. They give a nice explanation of every type of job - brake, rotor, or strut replacement, oil change, tune-up, all filters, etc. Pretty much anything you want to do. This is the bible for all E46 owners. You'll come back to it everytime.
