Mopar Only Shows

Here's a differing point of view for consideration. Our club, Inland Mopars, holds our annual "Mopars In May" all-Mopar show as a charity benefit show for the California School For The Deaf in Riverside (SoCal). Our 13th annual show will be on the school campus on May 19, 2013.
We have a "Non-Mopar" class because current students and alumni from CSDR are welcome to bring their cars and show them, no matter what the make.
Because of the show's reputation, we generally get 150-180 of the finest Mopars from SoCal and the surrounding area. We may get just a handful of non-Mopar cars.

First off I think its great that you guys do this for charity. My issue is when its advertised as "Mopar Only" and then it's not what you went for. I am in a different state of mind when I go to a "Mopar Only" meet vs an open meet. Why couldn't you just say that it's a car show sponsored by Inland Mopar? I have seen this done by other clubs both Mopar and the other guys clubs. This way you know what you are going to. To me only means only. To use my previous example, when you show up at a 72 and older only cruise with a 73 they say sorry but your car doesn't meet the requirements and you can't come in.
