Car Show vs "Show and Shine"

First off Idaho isn't anywhere in the ballpark of the population that Minnesota has so I can't imagine there even being closely the amount of cars and car shows or show and shines.
Show and shine could be also interpreted as a time to show it and maybe interpreted as a time to shine meaning a time to show and be accoladed.....
I've always considered a car show more of an event where people are competing for a trophy and a show and shine is more they just show up and a time to let your car shine.... As in reflect the sunlight...
