As for Chevelle shows;
Although I've taken home awards over the years at Chevelle shows, you have to wonder what the folks were really thinking in a participant judged show, (if it was because of having the most friends there?)
I'm sure that some are truly voting for the vehicles that they feel are in fact the best, but you never really know.
One time I won top three award because my car was the only one in the class
Most Judges at judged Chevelle shows are not really qualified for the year of car that they are judging but they do the best that they can.
Of course, best paint, or best whatever doesn't take Chevelle knowledge.
The old NCOA shows with the 1000 point judging were the only Chevelle shows with true honest judging.
To me, a show is not about winning an award or just about the vehicles, it's about the camaraderie, visiting with old friends and meeting new friends that share the same interest and the "car talk"
I really don't care for shows that allow newer vehicles myself but I suppose they have to be included to make the show profitable.
BUT, a room full of trophies and plaques is always impressive to non car friends and family.
