I've seen some reference to, and had recomendations from people that I check my vehicle's records to see what work has been done on my ML320.

I've done a lot of travelling and have had the car serviced at a number of dealers from California to Washington to Missouri.

Do I have to go to a dealer to get this info (and how many $$$ will they charge me) or is there a way I can access that info?

To my knowledge the dealer will print that our for you for free - all MB dealers are in a network - so I am referring to any MB dealer. Hope that helps.
