As for bonding, I had a slight problem with my Honda.
Seems that the exhaust system was acting as an antenna
as Honda Accord uses rubber hangars and bushings
to support everything from the exhaust header to the
muffler. They do this to reduce vibration. I made up some
6" grounding straps using braid removed from an old piece
of RG-8 and grounded the muffler, midpoint and cat-converter
case to the frame or engine. Put additional pieces between
the fenders and one on the steering shaft case. Finally I sprayed
a conductive coating spray on the inside of the rim across the
tire sidewalk (inner not seen from outside via underneath of
the car) in a strip to the tread edge to dissipate wheel static.
All the noise I had before on the radios completely disappeared.

I tune between stations on the AM band when I drive around looking. Of
course,
holding a SW portable out the window works, too, and allows getting out
and
confirming the source. You'll note that the noise tends to rise and fall
along
the lines due to, I believe, harmonics.

If the noise is internittent, check out the pole transformers and street
lights.

I don't like my Ford for the same reason. I believe Chrysler is the only
one
that fully bonds everything without special order. At least they used to.
Else,
ask for the police bonding package.
