I have a friend who wants me to do a tune up and maintenance on her 300E, and I have NEVER worked on a gas MB, so I went to phil's ordered up a good set of tune up paraphenalia (*SP?) and am getting ready to start next weekend,
I just wanted to know if there is anything particular I should look out for?
Crazy girl has NEVER changed her oil (although it leaks pretty bad, so it almost always has fresh oil, but filter never been changed!@*#*($#))

) her Distributer cap has been cracked for years, and it is difficult to start due to condensation in the cap... so of course I ordered full set of DC parts and plugs. I think I will skip the wireset. 102 for the CHEAP set of wires. I am getting two mahle Oil filters one for now and one for 1000 or so miles later.
looking for any specific or recommended points to inspect on this during tune up.
thanks,
John
