The 1955-57 Thunder-birds introduced luxury features to the two-seater market but buyers made clear that what they really wanted was four seats. The 1958 models were much larger cars with four seats and a unibody shell. They were either convertible or hardtop with a big-block 352ci V8 engine. There were few differences for 1958 and 1959 but the 430ci engine was added to the range. 1961 saw a very different body; a pointed nose and discreet tail fins and a 390ci V8 was added to the options. 1962 brought a Sports Roadster and the Landau model. This is a book of contemporary road and comparison tests, technical and specification data, consumer analysis, new model introductions, history. Models covered include: 352, 430, 390.
