It's got free shipping! How can I possibly resist?
For idiot sellers like that, if you can put up $1800, just buy it.
Then when it comes, take out your magnifying lens and 30-megapixel camera and ultraviolet light and go over it. Record every single micro-crack and speck of dirt.
File complaint with pp or cc company. Say that it isn't worth $1800. Remember, paying $1800 for 'good condition' means the condition has to be damn damn damn good, not 'thrift store good'.
You are guaranteed to win. Return it and laugh at seller.
