This is my entire spreadsheet, for the two years that I have owned my 2002 E46 330ci. To be fair, I did a lot of preventative maintenance, less so when it broke. When I waited for it to be broken, it usually cost me more money than to have done it as preventative. Also, when I do any work on my car, I don't like to skip any steps, no matter how minuscule it could be. So a lot of the costs can be skewed by how thorough I was with the job (fix).
After everything I've done to it, I would say it was worth it. This was proven to be when it performed exactly the way it should have, with no hiccups or a tow home from the Ridge.
