1976 Ford F-150 custom with 1900 miles

I found this 1976 Ford F-150 Custom on my
grandparents neighbors land, it has barely
any rust, the only two rusted through spots
are on the tailgate, it had 1912 original miles,
was brought down to Florida from South
Carolina and when it was up there it was kept
in a garage for 20+ years and driven only a
couple times a year and it ran 2 years ago, I
was wondering with all this in consideration
how much this truck would sell for, he wants
$8,000. Have many more photos, interior is
almost perfect beside a couple rips on the
driver side part of the bench seat, it also has
a small dent on the pool barn falling from
hurricane Irma
