Firstly, welcome to the forum.
Secondly, we have a dedicated For Sale section for posts like these.
Thirdly, as you will see you need 10 posts or more to be able to advertise in the for sale section. This is to curb newbies, who is just looking to sell their stuff and then leaves, in doing so.
Anyway, hope you stick around and become a regular, then you can gladly advertise your car here, and also meet a lot of new friends.
