Bill is right in the ball park 5 grand it would have to be clean and with out any rust These cars were known to rust look realy good on the top of the fender above the head lights It must be a plaza or a savoy as it has a flat head six belveders all came with v8s amd more chrome trim on the sides a 2 door belevder is worth more money the flat head also came with a 2 speed power flite still is a neat car

so the question is leave it stock OR build a sleeper

me I would pay about 3-3500 for a plaza or a savoy
the picture of the one I saw at alantic city back in 05 was a a plane jane savoy I did not look fast BUT with that 440 in it it was a sleeper and a fun car
