Hi. I would like to spend a little less than $2500 on this item. Is that something you would be interested in?
I honestly can't go that low. It's a great van. Very reliable and clean inside and out. I can consider $3500.
Looking online, I saw a few similar products going for $2800. Are you able to do that, as the van is 14 years old
I don't think you can find one in as good a condition as this one that low. I am willing to negotiate, but I don't think I can go that low. 
You want $3500 and I want $2800. How about we meet in the middle and settle for $3150? That way we both get what we want.
I think I can work with that. Do you want to come take a look at it?
Sure. I will come look at it tomorrow.
cool.
