MC,
Hang in there just in case. It's always refreshing to know you are not wanted unless they can't sell out. The Porshe clubs pull this crap all the time. Your good enough to run with them if the event might be cancelled but not good enough to sign up early.
I hate running with single Marque clubs.
or
Why don't you tell them you have a real Cobra but you prefer not to chance any scratches so you will run your Mustang. I think they let others do that.
