I also remember a 1969 XL GT Sportsroof with a 429 in town. It was black with gold C-stripes. The owner ran baby moons on it and chrome exhaust extensions. I last saw that one in 1973.
I also recall a 69 SS427 Impala Custom Coupe in town, Cortez Silver with red buckets & F41. It had a TH400 & Rally Wheels. An occasional sighting in Ancaster since I moved into the village proper in 1970, I last saw it in 1977 at Didero's Texaco getting an overhaul.
