I recently purchased an 05 SL500 with 27k miles. It has nav, keyless go, and comfort package. I noticed that when the engine is running, the incandescent lights "pulse", getting dim and bright. If I turn off the engine, the pulsing stops. There is a bit "hunting" in the engine at idle as well, which I would estimate to be +-100 rpm.
Otherwise car runs great...plenty of speed in the starter when turning over. Engine Rpm are stable above idle, although pulsing continues.
