These are very nice bikes according to a friend of mine that bought a new one in the late eighties. He broke it due to a crash and we couldn’t find him a replacement so he ended up with a 1973 Paramount . I have seen decent return on Circuits but this one is real small and like my tall bikes they take a certain rider with unusual size frame . That one is in very nice shape and with the right buyer I would say about $600 at least but I know nothing about your area. I have seen at least one in a 56 or 58 cm frame go upwards of 900 but that was a while ago .
