I know this is a subjectiv matter...but I know what my 65 El-Camino about worth and what my 85 El-Camino worth, but am lost on the aprox value of a 72 El Camino

It's an True SS 454 LS5, auto , AC ( works ) PS PB Cowl hood bench seat, with
12 bolt 3.36 ? posi.. Red ( what elce )black strip and vinyl top( orginial paint in bed and rear 1/4's )
Front end was re-painted and a 3/4 nose put on in 1981.. real clean all orginial

Agin not being a late mode type I have no Clue to it's value.. I see a WIDE WIDE margin on cars listed on e-bay and on team Chevelle ..

Thanks...
