Think you'll be waiting a long time. Personally, I hope that you get it because it would only mean my '65 Monaco with a 413 4bbl would be worth a lot more. But according to Hagerty Insurance, which I have found to be pretty spot on with car values, a 426 4bbl automatic in #1 CONCOURS condition would only be worth $25,000. "Condition #1 vehicles are the best in the world. The visual image is of the best vehicle, in the right colors, driving onto the lawn at the finest concours. Perfectly clean, the vehicle has been groomed down to the tire treads. Painted and chromed surfaces are mirror-like. Dust and dirt are banned, and materials used are correct and superbly fitted. The one word description for #1 vehicles is "concours."
"In #4 FAIR condition, according to Hagerty, it is worth $9,000. The description for Fair condition is; #4 vehicles are daily drivers, with flaws visible to the naked eye. The chrome might have pitting or scratches, the windshield might be chipped. Paintwork is imperfect, and perhaps the body has a minor dent. Split seams or a cracked dash, where applicable, might be present. No major parts are missing, but the wheels could differ from the originals, or other non- stock additions might be present. A #4 vehicle can also be a deteriorated restoration."
Yes, a 4 speed would add to the value but I don't think it would be $11,000. Plus, the FAIR condition rating is for a car that runs and is drivable.
