I sold a 59 Coronet 4door sedan two years ago for $8500. It was a nice running 326/Powerflite car painted in red and white. Had some rust in the floors and some spots on the body had been filled with Bondo or JB Weld, but very presentable with a "backyard" restoration. A 2door would have gone for more, but are harder to find.
I currently have a 58 Coronet 2dr Hardtop "Spring Special" that I plan on selling this summer. White car with a 325/Powerflite engine/transmission that has had the floors replaced and then the restoration "stalled". It sat for a couple years and needs some body work, but will be a beautiful car when done.
I also have a 57 Coronet D500 Hemi 4dr Hardtop (not sedan) that I need to sell (I am turning 75, and don't have the energy that I once had). Red and white, with the 325/Hemi/Torqueflite. Pretty solid car that needs some TLC in a couple spots that I started working on last Summer.
Both cars are located in Ohio, and if interested send me a Private Conversation and I will take some pictures. I plan on listing these cars later, once I get a few things sorted out on them, but if anyone is interested, you can save some cash by saving me some labor.
