 HI everyone, I bought my 06 Mercedes s500 with only 40k on it about a year ago and put about 60k on it. The car has 100k now, but here is where the horror story begins. At 100k the Service needed to be done (Spark Plugs, Oil change, all lubes) $560 and $2000 at the dealer. After two months the SAM went out, my TPMS sensors went out, Brakes went out, AIRMATIC PUMP went out and the car sat to the floor, The Secondary Air Injection went out. This car is very beautiful and comfortable and I used it a lot. If I went to the dealership I would have paid over $9000 for all of those services i mentioned above, I am not that type to go to the dealer but $4000 is still not a cheap price to pay. This car has many pumps and gadgets that can go out, be prepared to replace them at 100k! After that hopefully it will go for another 100k with normal maintaining.
