Hi all,
I now have a little more clarity on something by boxster does:
Background/Description:
2001 box, 38K miles, tiptronic trans.  Currently in upstate NY
When I try to start the car in the morning (lately), the car engine will make a strange sound.  It will vibrate and shake the slightly car back and forth - maybe a few times a second.  This is clearly unnatural and problematic.  What I have determined is that if I start the car and leave it in neutral, this will not happen.  If I put it into reverse (or drive) it will do some shaking.  The temperature is somewhat cold (40 degrees?) and I have not observed this on a hot day.  What might be a cause and its severity in you opinion?  
Second question:  
This seems a little odd to me and I was wondering if any of you have experienced this - if I just start my car and drive it around (not warmed up) and run it at 1.5K RPM or less (especially in 3rd+ gear), I heard a slight "dragging sound".  It seems to be something rubbing or causing friction and seems to come from somewhere behind the driver side (maybe near/in the engine's compartment).  I do not hear this sound when the engine is fully warmed up, even if it gets run at a very low RPM in gear.  Anybody experience this?
Thanks!
