What do audiophiles listen in their cars?


I know this is not a car audio sight, but it would help me out a lot if I could get input as to what the discriminating audiophiles listen to in their cars.

If you can give me a detailed list of the system, I would really appreciate it - I am starting an affordable Hifi shop that includes car audio.

Thanks a mill. in advance...

In my 95 Chevy with all the wonderful road noise :) I listen to either talk radio or a local jazz station that sounds as if they are broadcasting from underground.
I'm like Ghosthouse. Engine, driveline, tire noise (road texture), wind noise.

Used to love car audio when I was young and hung out in cars a lot, but the noise floor is too high in my commuter. It would be money better spent on upgrading my home gear.
