One of the largest weekly automotive gatherings in Houston, Texas, has announced in an Instagram post that it will permanently ban late-model Ford Mustangs, Chevrolet Camaros, Dodge Chargers, and Dodge Challengers from its events. It’s unclear exactly how far back one must go in order to qualify as a non-modern muscle car, or if it varies by model or package. In any case, modern muscle enthusiasts will have to find another avenue for Saturday meetups as of this writing.
