  While on this subject...
  I've yet to figure out exactly why a Rabbit vs B4 Passat has 
such a HUGE difference in coasting speed/resistance.  I was heading 
down a canyon in the pu yesterday and it held speed limit all the 
way.  Coast the Passat down it and it'd have been up to 80mph 
or better!  I know there are a lot of little things but geez.  It's almost 
like a brake is part way on.  My Rabbit was comperable but slightly 
better than the pu, yet NOTHING like the Passats.  Those things 
fly downhill.
