$600 is not bad for a AM/FM radio that has current technology. An original AM/FM Delco, untested that may or may not work will set you back $3-500. Add another $250-350 for cleaning, testing and repair and you have a correct concour ready radio.
I say go the repop route if a quality piece. If you have a rare one of 100 car, by all means originality it away!
Looks like a good piece though. I really like the MP3, IPOD, CD or XM (satellite) inputs. Really good for cruises without the headaches of splicing or wires. And the rear of the radio offers plenty of maneuver space. Easy IPOD or XM docking with an original look? I am sold.
