Here is a very clean '57 Fairlane 500 that is in my area and I have looked at. It was originally built by a Ford Mechanic so the fuel injection conversion is very factory looking. He started with a nice clean original car. It is not flawless or a show car, but a very presentable and solid car. Looks like it could be driven anywhere. If someone is interested I can go look at it again to check any details.
