Am I Being Unreasonable? Original Owner Wants Car Back

So in your post you said:

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.
I told him north of $40k to buy it outright or if either of us find a replacement that I like that's the price (+tax +shipping). A lot of the advice you all are giving is almost word for word what I told him.
