Its a good looking Charger. If there is no or minimal rust, I'd say 8-9k? I dunno.
That's a good starting price. People will try to low ball you. Make sure you have a firm idea of how low you'll go. It does look like a nice car and with the 318, a nice cruiser with decent mileage. Is there anything special in particular with this car that will help sell it? Build sheet? interesting options? Looks like a nice stock example.
A while back someone here was offering a Charger this body style, not sure what year, but it had a 440, Six Pack hood scoop, orange, set up nice and was fast. I THINK that one was selling for like $12-14k. I can't quite remember though.... another Charger this body style, stock, forget the engine, maybe a 340-383, blue, with Keystone Klassics was asking for like $10-11 I think.....
This is a cool body style. I like to do model cars and there is a cool 1/16 scale Charger Street Machine model that is sweet, IMO...
