My starter went out on my W166 recently, waiting to hear back from the mechanic shop on specifics but I figured someone here could give me a general answer.

My question is, given replacing the starter, how easy is it to replace the spark plugs from there? I will need a timing chain job done in 10-20K miles or so, would all the plugs be significantly more accessible during that job vs this starter swap?

Overall goal is to reduce book hours and therefore cost 😅
