Picked up car at AZ dealer, noticed pulsing brake pedal stopping. Obvious warped rotor(s). Installed 4 new, HD, drilled rotors, ceramic pads and new Dot 4 brake fluid. Fixed all brake problems. Stutter while accelerating when cold. Also had inspection after recent purchase. Engine oil leaks, suggested new plugs. Oil leaks were "on the top, front of engine", not fixed, but that was fine with me. I plan to replace the spark plugs so I would have to disassemble the complicated air cleaner and I can see if it was from someone overfilling and dripping oil or actual leaks. If leaks I am a DIY guy. Cold stutter is still there, but it seems to be less and less. Since they recommend plugs at 60k, I am hoping that changing the plugs will correct the problem.

At 60k, MB suggests a new serpentine belt. Since this is a new to me car and I was doing other things, I decided to replace the serpentine belt. I ordered an AC, but it was too long so I reordered a genuine MB belt from Amazon and it fit perfectly (at twice the price).
