IMO, mutually exclusive.

The dynamic range which you can obtain in a car is just not sufficient for high quality audio as anyone who listens to R3 in the car in the UK will probably testify. You just can't hear quiet passages. If you put in compression to fix this, is it high quality afterwards?

I'm not saying that you can't get a "nice" sound in a car and I am a motoring enthusiast myself (see avatar) but high quality?
