More than likely, any '65 Chevy police car would have been a 4-door. Not sure if there was a 4-door Impala; probably a Biscayne or Bel Air.wildbill63 said:That says "Illinois State Police circa 1965" all over it! Don't know if we actually had '65 Impalas for cop cars or not but it sure looks like it could of been. I like it, looks cool, 396 cubic inches(not counting the '63 mystery moter) of big block, hooligan catchin power. :thumbsup:
