People dig the retro "rat" look. A car that looks like it has been sitting in a paddock or a barn for years is more visually appealing. A car that you make look really nice isn't that appealing to most people and they won't spend up big on them. Unless it's a commssioned job, just either restore to factory or get it running and driving as is.
Having a laugh at "Turn and Burn" at the moment, some of the crap he has go through his workshop. I wouldn't buy a car from him unless it's as he found it.
