2008 S550 - surge foward ...
I test drove 2008 S550 71k on it
Drove nice on highway but in parking lot at low speed a stopped then let of brake
The car surged forward - not allot just a little - like a buck
This happened a couple of times but not every time - Car was in summer setting
Engine seemed to be running smooth and quiet
The car was hot as it had been driven 1 1/2hour to get to me
Does anyone know what could be causing this
The car was perfect other than that
Please advise as I am trying to make a purchasing decision by tomorrow

That is a software bug in the tcu. Was introduced a few years ago. There is a software fix for it. It has to do with tranny engagement after a complete stop disengages it to improve fuel economy. Mercedes calls it KID.
That or adaptations need to be reset- but it is usually the KID acting up.
