Did our cars come originally with a service book , I don’t have one, but I have my cars main dealer history printed out from sytners.
I was informed yesterday as I booked it in for service it should have come with one !
Probably it's gonna depend when yours was first registered? My 2015 model did come with a conventional service book. However Mercedes had phased them out by 2016...
My Sept 2016 35is came with a service book - Out 335 xd July 2015 did not! It is all stored on iDrive
I keep all receipts i a folder so its not a problem if I sell privately.
