Somebody mentioned the 2 ft triangular absorber that is used in RAM.
This is not the only kind that is available.  I use a type of RAM that
looks like a piece of vinal but is much heavier.  The frequency range
that it is used for is from 2 Ghz up to 26 Ghz.  Cost is approx. $55/sq ft.
Works well for what I need it for but I don't know how well it would
work on a car.  There is also another type that looks like black 
styrofoam (sp) but is flexible.  I have used this type down around the
3 to 5 Ghz range.  This type is much cheaper (I forget the exact price).
Neither of them have the funny triangular look.  Just to let everybody
know.
