Back to the old trade fairs

This Autocade article brought back memories of the World Trade Fair at the Wellington Show Buildings in 1979, which I attended with my mother. Škoda, Hyundai and Volvo showed off their cars at the Fair, which in my opinion was never equalled with subsequent school holidays. I picked up the Hyundai Pony brochure and believe it had this photograph in it.
   What happened to those great, open-to-the-public trade fairs in New Zealand?

Hyundai Pony. 1975–85 (prod. unknown). 3-, 4- and 5-door sedan, 5-door wagon, 2-door pick-up. F/R, 1238, 1439, 1597 cm³ (4 cyl. SOHC). ItalDesign body—Giugiaro also did the original Volkswagen Golf—was smart and crisp for Pony’s 1975 launch, but it hid a structure that essentially followed those of the Morris Marina, mated to Mitsubishi running gear. The brainchild of George Turnbull, formerly of British Leyland, who believed that a simple platform such as the Marina’s was far more adaptable than BL believed. Engines aside, pretty dated technology even when new, but sold on simplicity and cheapness, and took Hyundai into many export markets in the 1970s and early 1980s. Usually takes the credit as the first all-Korean car, despite the foreign input. Pick-up added 1976 after original hatchback, wagon in 1977, three-door in 1980. Replacement Pony II began coming on stream in 1982, after which original range rationalized and replaced by 1985.
