Actually not a scam - that car is a '71 3.5 cabrio, apparently restored to a very high standard. May not be your way to spend (now) 61 large, but it's still got a ways to go. I would guess the reserve is at least 70, maybe 75.
These are very nice cars, highly valued by collectors. The money goes for the cabrios, even the 3.5 coupes are generally worth half of the cabrios. The rest of the late '60s - early '70's cars, with the exception of the SL's are not valued very highly, at least financially.
