I agree with Dkarmeli, I don't know of any good ones currently on the market, but there are a few which have recently been discontinued which are very good.
Look at any of the following:
Pioneer - DEX-P99RS - this still may be available, but I'm not positive. I have one and it's fantastic.
Nakamichi CD700II - easily the best head unit I've ever heard and also own one. It's long discontinued however.
Macintosh MX-5000
Clarion DRZ-9255
Do a google search of "DIY mobile audio forum" and you will find the Audiogon of car audio.
Good luck.
