S197 Mustangs were in abundance at the anniversary show. From stone stock '10s (some of which were rental cars driven by Mustang enthusiasts from other countries) to highly modified GTs, Saleens, Roush packages, and more. One of the more pleasant surprises was Joseph Higgins Jr's Pony Package V-6 S197. With an aftermarket hood and wheels he had the outside looking quite spiffy. The real eye opener was the Explorer Express X-Charger supercharger system under the hood. A blown V-6 has got to be fun in an S197.
