This is a one owner car. My father bought it for my motherin 1964 as a wedding present. it runs great but my motheris 91 and doesn't drive it. it sits in the garage covered andis dusted off cleaned and demoused once a year. All originalexcept for the rear bumper which has been replaced do toa small dent.
