Can anyone help with the value of this car?

Ok heres the deal. My grandfather passed away about 10 years ago (R.I.P.) and left his 1972, straight six, demon to my uncle. After years and years of bugging him to sell it to me, he is ready to part with it. From what i remember as a little child around 5 (im 30 now) it always looked like this and he rarely took it out on the town. After my uncle got it, it has done about the same. It runs and drive with no mechanical issues. Except rear seal on the pan drips, it has a few paint chips and the front seat is ripped other then that i cant find anything it might need except maybe a good clean up. Im not a mopar guy and im wondering what the car would be valued at (roughly) obviously with out seeing or driving it, its hard to judge. Any help would be appreciative, or things i should check on these cars before buying?:sign3:
