I cant find a blue book value for a 1984 chevy el camino conquista edition. It has 40,000 miles on the chassis and engine, and the engine is a ss monte carlo 5.0 liter v8. Car isnt in absolute perfect shape but nothing major and nothing even noticable unless looking closely, (few hail dings,scratches in truck bed) but works mechanically 100% and body and interior is clean! AC, Heater and classic motorola cassette and radio!
