Ed,

	This is VERY true.  I have had the distinct pleasure of driving 
cars on GM Proving ground roads where they have samples of virtually 
every asphalt/concrete road type in existence.  There is one loop in 
Mesa that is about 5 miles long, with three lanes, where they have a 
different road surface every 500' or so.  You can get a feel for how the 
tires sound really fast with this kind of repeatability, and consistency 
in the test.  They also have alot of other very interesting roads.  It 
really is a great place to test a car's capabilities.  I was in an LH at 
Chrysler's Poving grounds a couple years ago.  The driver was a 
racer-friend of mine.  He was sliding this Intrepid through big sweeping 
turnsat 75 - 80 mph with all four wheels sliding!  Then he went through 
one at over 75, and there was a HUGE bump in the middle of the turn!  That 
LH just soaked it up, and kept going!  Yeah, it slid sideways a little, 
but it was all very controllable.

	Boy I'd love to get my Quattro on the track to see how it 
compares.  I think it would do OK compared to our new Caddys.
