Well I just left the dealer for the "A" service on my 2007 Mercedes Benz C280 4Matic and actually chuckle'd at the bill. Only 13,212 miles on it.
I ask'd; What did you do for $500..............well sir, we change the oil and filter (synthetic, oem parts), check undercarriage bolts and fixings, checked belts, road test, rotate the tires, reset maintenence light, and wash. And sir, you will not need another oil change for 14 months or 10k miles.................thank god, I can start saving now.
I came up with maybe $100 tops, OK its a Mercedes.
Gotta luv it
