Hi - For those of you who do your own maintenance, what reference books are you finding most useful? On other car's I've owned I've typically used Haynes - which seems to offer a 3 Series book covering the M42 and M44. I also looked at the more expensive Chiltons which covers a wider range of years and models (not necessarily a good thing).
It does Rock! I'd be terrified to try anything more complicated than replacing plugs, filters, etc without a good manual in front of me though. A picture's worth a thousand threads right?
