1967 Newport coupe value?

Hi Guys, I have a chance to buy a 67 Newport coupe, black on black, 383 high compression with 4 barrel, and only 25000 miles. Fold down armrest no console shift, new brakes, tires and painted once, 20 years ago and a few small rust spots, not deep rust.
My problem is I dont have a clue what its worth, and havent found a lot of similar cars to compare it to. Any rough estimates? Im in love with it already so please help this relationship along, Thanks!
