I'm new to forums and just figuring them out....here is the problem. I'm buying a 560sl, the badging says 560sl, the title says 560sl, but here is the issue......the title also says 1981. Now I know that the 560sl started in 86, and the 3rd brake like is consistent with a 86,87 model. The Vin number comes back invalid. It also have what looks like factory wire wheels, but I can't find anything out there that matches or makes sense. Did I buy a mistake?
