It all depends on who you talk to within Mercedes, engineers or marketing team.Maybe the first oil change, but there is no reason for 3000 or 5000 miles oil changes. Oil are synthetic now and there are 10 quarters in there, there is no need to waste perfectly good oil. I do agree 20K is probably a little bit much, but 10K is no problem. I live in an area with high cost, prepaid can really benefit me. That's why I am checking to see if I can get a discount. It's not that I want to pay dealership the money, but I have to do it for warranty purposes.
Hey, I just SHARE the info. Up to consumers to decide whatever maintenance they deem acceptable.A car that gets driven harder will need to have oil change earlier than cars that are driven easier? It's nothing new. The 1 year 20K is a base line. If you race the car on track, get it done sooner. If you are driving normal, I am not seeing why I need to run out to the dealer every 3000 miles to replace 11 quarts of oil.
