I think spark plugs are 4 years or 60k miles.The car I’m going to see on Monday sounds and looks pretty good going from the full service history. All MBZ main dealer and then the same Indy MBZ garage. 81k on the clock and 2 owners previous.
ATF was done at 40k but not since, and it seems to suggest it’s never had a spark plug change as the box has never been ticked on any of the records. Is that just done with a B service as standard?
I had read that they don’t need changing until 140k so that would explain it, assuming that info is correct.
Is there anywhere I can see what the service schedule is on a 2007 SL350?
