Fix, sell or trade in?

14 yrs we have had this. With no major issues. Just wear
and tear type of maintenance. In 2019 it broke down while
someone borrowed it. We got no info regarding what took
place. Got it towed home but didn't have time to or
finances to pour into it until 2020 but by then covid
happened. So not until now we're we able to get it checked
out. We replaced waterpump and tires $1,028. . So we
found other issues during replacements we do t know
what to do. Fix and hope nothing else is an issue. Sell but
for how much ? Take in and take a huge loss? Please give
us some suggestions and opinions even guesstimates so
we know we aren't being screwed.
Waterpump replaced and belts. Noticed spout for hose
from radiator is cracked so we know it will need to be
replaced..
New tires showed all ball joints ,arms , rotors , struts and
shocks need to be replaced.
Ac isn't pushing out air but lights up. When it was towed it
still worked and was really strong and cold or hot when in
use.
