If we want to call it a DSM event, but still allow other cars, how about this: Come in a DSM or come as the guest of a DSM. Require non-DSMs to have a Club DSM member invite or "sponsor" them (kind of like vouching for them that they're "cool"). That should keep the event "Private" & between friends
