I know it keeps the warranty in effect. But $300 for a oil/filter change and hookin the SL to a computer to see if it threw any codes is kinda high Well atleast I will only have to do this once a year. I had 4700 miles on mine when it came up on its mid August build date. So the oil is 1 year old and it has to go, no problem I don't want old oil in my SL but $300 is

 

You must also check that the crafty buggers have set the oil to 229,5 otherwise it will be back in soon for another service
