Shortly after the halfway point of the show, Perry Mason is shown exiting a 1962 Ford Galaxie 500XL convertible and climbing the stairs into the Los Angeles district courthouse building. This was a shot from a Season Five show, re-used frequently for stock footage in subsequent shows until the series ended in 1966. Mason almost always drove a latest-model, top-of-the-line automobile from Ford Motor Company...in the first three seasons, Ford's "halo car," the amazing Fairlane (Galaxie in 1959) retractable metal hardtop convertible; Seasons 4-9, a Lincoln convertible sedan. (On occasion he would be seen driving a Cadillac instead.) He'd never be seen driving a four-year-old car in 1966.
This is the third time in the series that Perry Mason testifies on the stand against his client.
