Here are a bunch more photos, all from episode 6.8, "The Taylors in Hollywood." All of these cars have one star roles (background).

1959 Cadillac

(plus several others including two Lincolns and a '64 Chevy Malibu)

1963 Dodge (Polara?)


1964-65 Ford Mustang


Chevrolet Greenbriar Van


1964 Chevrolet Impala


1965 Chevrolet Impala


1960 Chevrolet Impala

(that also looks like a Buick in the foreground)

1961 Chevrolet Biscayne


Fiat, year unknown



...and that should pretty much do it for "The Andy Griffith Show," season 6.
