Volvo C 70 no demand for sale

Hello, I think about a vehicle change after and started 3 months ago to offer my convertible from 2007 at (mobile etc.) . So far there was almost no demand ? That has surprised me very much , because a mileage of 130000 is for a diesel yes not so the problem . And also optically he makes still a very good impression . I still need for me a Combi , and would also want to stay with Volvo again . That it is Nov. and one can sell a convertible worse in winter is already clear to me . It is also not an emergency sale , but that no buyer finds me already thoughtful . What do you have for experiences .
