In the Long ago, there used to be a "Northern Illinois Shelby Club" that carried the torch there. They are all gone. And the used to be a MCC (Mustang Club of Chicago) way long ago. And plenty of other Mustang Dealer sponsored clubs. Like Bar CB (C. Bradshaw Ford), Perno, and many others.
If it wasn't for THIS web site, likely there wouldn't be a Chicago Vintage Mustang Club. Kind of glad there is.
Now we have a new group of folks carrying the Mustang Torch. And, although the name says Chicago, most of us live in the suburb's. All you got to do is tell every Mustang owner you know about the VMF, and let them go to the local clubs.
I could see a Detoit Mustang Club.
Oh, no dues, fees. No newsletter (got the net for that) Meetings are posted. Car shows are posted. Nice and friendly folks.
