People throw around the term "survivor" a lot.
80% original paint
Original engine paint. Never opened more than a valve cover.
80-90% original interior
Low mileage- under 70K at most
That's about a minimum. Good examples have original spark plug wires, orginal hoses, belts...
Let's see a engine compartment shot of that Charger?? The added 68 side markers, carb, and ign. hurt the survivor status. If the motor hasn't been repainted ever and its' got 80% original paint and interior I'd give it survivor status.
