Hello, and thank you for your question.
Please tell me what the color scheme is, whether it works well, and about the over all condition, inside and out. All original?
In that case, all cleaned and prepped for sale and assuming the warping/ weather stripping is not too obtrusive/ detracting from the "appeal" of the unit, it would be in the range of about $400-$600.

Thank you, again.
