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...

BMW 330i Coupe. Superb audio system. Radio has HD capability. Use aux/USB input for iPod or iPhone. Sounds grand. Only problems are BMW has a custom cable with dual USB and aux inputs which must be used simultaneously, and I have not found an upgraded cable to improve sound. Also, run flat tires create a lot of road noise.

I could care less about car audio. I mostly listen to sports radio on the daily drive which doesn't require a fancy system. The radio in my 95 BMW died and I replaced it with a Kenwood from Crtuchfield for 160.00. This thing has features that are unbelieveable for the price and it sounds better than the original radio. I did the install myself.

I think a lot of people are into their car audio because of domestic restrictions from wife, kids, neighbors, etc. In their car, they can let loose and blast music that is not possible to do at home. Thankfully, I don't face that barrier.
Not being sarcastic...
But on long drives, very often...just the engine, road noise and the wind.
I do all my listening at home as it is my passion but listening to music in the for me is distracting. I am a casual listener when it comes to driving. Half of the time I do not listen to music when in the car. Talk about room acoustics and noise in a car.......let's leave that for some other time.
