engine harshness at high revs

Are you feeling that through the steering wheel, pedals, shifter, etc? Tomorrow if the rain is gone I'll go for a drive in the morning and specifically pay attention for it so I can compare.

Is it possible I just don't have enough miles (around 2000 miles) on the vehicle? I'm not detecting any significant vibration yet I can feel every nook and cranny on the road...

There is an inherent Harshness factor with this motor, but it does seem to vary a bit between cars...
