I have a question regarding car stereo. I have a 20 y.o. system which has seen better days in my '72 SSP It looks like a jukebox (big chunky AM/FM radio-cassette) and I want to upgrade to CD/MP3 etc. The player is under dash and held in by a couple of screws / bracket (it was back in '91), so drilling 2 holes was not such an issue

I was thinking about a compact under dash AM/FM/CD/MP3 (preferably removable, or with a removable facia. My SSP also used to have a one of these tape recorders on the center console (long gone, but mounting point still evident), so I was thinking I could put a AM/FM/CD/MP3 in one of those consoles.
I am not looking for a super stereo you can hear from 5 block away - just something to provide good sound (audible above the engine) to make longer trips (and shorter trips) more enjoyable.
What do you have in your cars and do you have any pics / recommendations?
Thanks for you input.
