I have been trying to start a "Car's condition scale" with some success. The scale is 0-5. Where "0" is really non existence sence you need at least a rusted out frame laying there to judge? And "5" being non existence sence nothing is "Perfect" ( I know the concourse have judged a couple cars "100" flawless. But I believe they didn't look hard enough. Lol.)
0.0 - 0.9 Is a frame, VIN, and or tag.
1.0 - 1.9 is a frame and shell. (Needs WORK)
2.0 - 2.9 is a runner Or very decent non runner starting point.
3.0 - 3.9 is a solid runner in very good shape or higher restoration beginnings of a non runner.
4.0 - 4.9. Show level and collector car quality.
Below is a quick walk around vid of my current street GTX. Because it's non numbers matching and/or not a higher end performance restomod? I believe it cannot be in the "4.0+" arena. Current condition I would consider a 3.2.
I believe 3.5 is what most enthusiasts really like. A car that can show decent. But not afraid to drive. Thus price would reflect that 3.5 rating. (Of course car make and demand is the other primary cost factor.)
