Gene, the problem is that there are too many definitions for "restored". To me, restored means that it is as perfect as when it came off the factory line. Some people think that if it runs good, looks good, and has new tires, it is restored. Others think if it was dead on arrival and they have it running with decent tires and a "walk around" spray paint job, they have restored it.
With all the above considerations, the most I have seen one sell for that could be considered a true restoration was $3,500 - and that was less than the guy had in it. The middle of the road restoration (around here) would bring about $2,000 to $2,500. The "walk around" restoration (around here) would be $1,600 to $2,000.
As in selling houses, location is also a major factor. Your locale could see totally different pricing than mine.
Hope all the above is of some help.........
