Hey, I was just wondering if I could have the benefit of your wisdom

Im trying to sell my 156 but so far no luck, can anyone help me with what they think I should be asking for it?
I paid $11,500 from a dealership in april and I know I cant get that much but I dont want to lose too much and when I was looking for my car I couldnt
find one for the price im asking for mine. for what you get (sunroof, towbar, manual, ect)
This is the link. (I am NOT fishing for sales in this post, I do have an ad in the sales section on here, this post is just for advice from people who know the cars)
