As discussed in another thread selling a higher valued vehicle especially a niche vehicle is not easy. Things like financing and trade in are a lot easier through the dealer. In addition the price can be an issue, the black book on your vehicle is around $21000 so a dealer could sell for about $ 23-24000 so you may have to take a bit less than the dealer. Not sure if the like below works, if not just google Canadian blackbook for the site
