Am I Being Unreasonable? Original Owner Wants Car Back

So in your post you said:
I've tried being creative with him and as transparent & flexible as I could be, but I can't even get him to throw out a number that would work for him, says we're too far apart.
So what’s too far apart? Did you throw a number at him? I believe you have every right to ask whatever you want for the car. Just curious as to how one can say that you’re too far apart when there are no numbers being thrown out.
