Selling a defected car

[HelpMe351]

Hi everyone I'm new here and I'm sorry if I posted this in the wrong section. I have a classic Ford that I acquired years ago, it was defected and swapped a going car for it. Firsty I need to sell it but don't know how to go about it because of the defect. Secondly I need to know the appropriate value of it. It's a Ford XA coupe with GT parts ( it's not a GT) it does have a fair amount of rust, interior is in really good condition. I'm older and not sure how this forum works and hopefully I can get back to my post!
