Absolutely Dave! Taking most any car to a car show is fun. Where else can you be around fellow car geeks?
Don't bet that you won't win anything. Most all local car shows have different classes and categories. Sometimes you will fit into some class where the other cars aren't as nice or maybe there are only a few cars in the class. If your car is nice, depending on the judging criteria, honest judges will be judging based on categories that have nothing to do with whether it's a Mercedes or a GT40.
Good luck and enjoy the experience.
