One of the new small family car stars of the 1959 Motor Show, the Herald was a bit more upmarket than the Mini or Anglia. All that really held it back was the lack of power from its 948cc engine, even in the twin-carb form used in the convertible launched in 1960 (worth a 25% premium) and soon offered as an option for the saloon. There was also a Herald S launched in 1961, but don’t go thinking that stands for Sport. It was actually a stripped-out budget model that continued for some time after the 1200 arrived and, though rarer, is the least valuable of the range.
