this is the only car I've ever had that I cant find a damn manual for. 2006 mazda 6. anyone?

A lot of libraries carry automotive databases. Some of thses databases are free, if you live in an area they serve. You can also buy access for a small yearly fee. You can access on your home computer, which makes it handy. MOD and ALLDATA both, you can buy access for a yearly fee.

I didn't look to see if they covered a Mazda 6? If the vehicle is sold in the US, they probably cover it.

actually found one http://www.eserviceinfo.com/download.php?fileid=35981 just download all 7 parts and unzip. also found ondemand5 although it is expensive it is an option if you can find a download for it.
