We have a 67 4-door that's been switched to a built-up 440 that's got a new interior and perfect body selling for $8,500 over here, which I'm sure it's worth but it's been for sale forever. I'm guessing it would move at $5,000, so I would value this car at $1,500 to $2,000 tops. The only thing there are fewer of than nice 4-door Coronets is people who want them.
