I am not that familiar with M-Bs but a friend wants me to do routine servicing on his 2008. I always like to have a factory service manual on hand but as they are expensive I see that Haynes has theirs for 2007 300s. I believe that 2008 saw extensive changes to the model but am not sure. Are the two years so different that info from the 2007 manual wouldn't be helpful-- for example -- as to fluid/filter change on the trans and brake fluid replacement/brake bleeding? Thanks
