It's a fair price, especially in this area. Conforms to similar items on CL locally as well.
Whether its objective worth is such is another question, but the market value is certainly in line with the asking price.
What is "objective worth" and how does one measure it?
For example, does the objective worth of a glass of cool water change depending on whether it is at hand in the Sahara desert or three feet away from a natural spring pouring out of a Swiss mountain?
If I was trapped in Northern Iraq for example, with ISIS on my tail, an old but reliable Jeep Cherokee would be objectively worth at least $10,000 to me.
Stuff is worth what people are prepared to pay for it. That is the only meaningful basis of establishing a price. What other people are paying for other Jeep Cherokees of similar age and condition is the only "objective" measure of value or worth.
