Marcos,
I agree....we would have to be our own judges, or assist with the judging. I think that the "standard" is the problem, though. There are many of us, on more than just the two sites, that have specific knowledge or experience with certain states, but there are many more cars out there that documentation doesn't readily exist for (for instance, the Kansas car that John M. just purchased).
Then there's the problem of figuring out what is correct versus what isn't, based on who you're asking.
I think it can be done, but we'll have to collectively figure out how the classes could be structured and make sure that we do so in a way that covers the majority of what's out there; from resto-mod type cars through the cars that receive complete, in-service-type restorations.
