I wonder when Ford took over Holden as the car up for grabs on the show as there are some more 1991 shows from earlier in the year on here when Holden was still the sponsor of the car. I'm just playing a hunch and guessing it was around mid-year, as it was WoF's 10th anniversary since it's debut episode in July of 1991 (that probably also would've been when the buzzer sound had been changed - this sound lasted through until to March 1994 when it was changed and by August 1994, it had been "shortened" to the more "familiar" buzzer sound that lasted the rest of the show's run)
