I just sent another one out last week for my 1975 stocker with 650 original miles on it. I always choose "Good" condition on the Nada value from Vermont pricing. Why? Because I don't want it sent back, ever. Sure, I end up paying an extra 5-10 in taxes over listing it as "fair" but I want to make sure they are getting their revenue...don't want this service to dry up anytime soon. And yes, i live in Virginia, and its never been an issue.
However, i recently registered one in VA that I had a VT plate on for several years. I went to 3 DMV's and all of them told me different things and different requirements. I went so far to tell one of them that they didn't know what they were talking about, picked my papers and left. I went to a mobile DMV and 20 min later was happy.
