I bought mine 10 years ago with obvious rust (and holes everywhere). I had no idea that I would bring it back to better looking than new. i paid $700 for a rust bucket with everything there and one wheel that would actually roll when loading it. 3 years and $25,000 later, i have a nice truck to enjoy. If you like how it looks, it drives and seems to be reliable. It may be wise to meet in the middle between your price and his and take that thing home !
