Terry Marvel has some great examples of vintage 70′s Ford Broncos in ads. Some are Ford magazine ads, while some are from different companies, like Minolta.
Bring A Trailer has what I consider to be a very good deal! Two early Ford Bronco’s for $4950! The 1966 is neat because that is the first year of the Ford Bronco and the 1976 has factory disc brakes and power steering. They appear to be in good shape body wise and both run and drive. A bunch of spare parts is part of the deal, including a rear seat, new suspension parts, new shorty headers etc…
