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...

Sometimes NPR, sometimes talk radio, sometimes "oldies" radio, sometimes the sound of the boxer-6 engine with the top down.
As the owner of an extremely great home system, I don't expect anything close in my vehicle, but do choose the best in factory installed systems. Integrated makes sense; after market only invites theft. As a classical lover, XM/Sirius is my choice most of the time. I look at it as an opportunity to hear music I don't already know, as as well as enjoy music I do. Granted, it is not the best FI. For the best, HiRez files from my connected iPod/iPhone can be wonderful and even thrilling!
