Summary: The Mini is a very small two-door, four-seat car, produced for four decades over a single generation, with many names and variants, by the British Motor Corporation (BMC) and its successors British Leyland and the Rover Group, and finally (briefly) under BMW ownership. Minis were built as fastbacks, estates, convertibles, and various other body styles. Minus a brief 1990s hiatus, from 1959 into 2000, an estimated 5.38 million of all variations combined were built, and the Mini’s engines also powered another 2 million Mini Metros, though the Mini eventually outlasted its successor. Initially, the Mini was marketed under the Austin and Morris names, as the Austin Seven and Morris Mini-Minor; the Austin Seven was renamed Austin Mini in 1962 and Mini became a marque in its own right in 1969. Retrospectively, the car is known as the “Classic Mini” to distinguish it from the modern MINI family of vehicles produced since 2001 by German carmaker BMW, who took ownership of the Mini name following the sale of Rover Group in 2000. This distinctive two-door car was designed for BMC by Sir Alec Issigonis. Its space-saving transverse engine and front-wheel drive layout – allowing 80% of the area of the car’s floorpan to be used for passengers and luggage – influenced a generation of car makers. The front-wheel-drive, transverse-engine layout were used in many other “supermini” style car designs such as Honda N360 (1967), Nissan Cherry (1970), and Fiat 127 (1971). The layout was also adapted for larger subcompact designs. In 1999, the Mini was voted the second-most influential car of the 20th century, behind the Ford Model T, and ahead of the Citroën DS and Volkswagen Beetle. It is also considered an icon of 1960s British popular culture. The Mini Mark I had three major UK updates: the Mark II, the Clubman, and the Mark III. Within these was a series of variations, including an estate car, a pick-up, a van, and the Mini Moke, a jeep-like buggy. The performance versions, the Mini Cooper and Cooper “S”, were successful as both race and rally cars, winning the Monte Carlo Rally in 1964, 1965, and 1967. The Mini was manufactured in England at the Longbridge plant in Birmingham located next to BMC’s headquarters and at the former Morris Motors plant at Cowley, as well as in Australia (Victoria Park/Zetland BMC Australia factory) and later also in Spain (Authi), Belgium, Italy (Innocenti, as the Innocenti Mini), Chile, Malta, Portugal, South Africa, Uruguay, Venezuela, and Yugoslavia (IMV). In 1980, British Leyland launched the Mini’s follow-up, the Austin Metro, however the Mini outlasted it and continued to be produced at Longbridge until October 2000.

Summary: The Nissan 300ZX is a sports car that was produced across two different generations. As with all other versions of the Z, the 300ZX was sold within the Japanese domestic market under the name Fairlady Z. It was sold in Japan from 1983 to 2000 and in the United States from 1984 to 1996, the 300ZX name followed the numerical convention initiated with the original Z car, the Nissan Fairlady Z (S30), which was marketed in the U.S. as the 240Z. The addition of the “X” to the car’s name was a carryover from its predecessor, the 280ZX, to signify the presence of more luxury and comfort oriented features. The first generation 300ZX known as the Z31 model was produced from 1983 through 1989 and was a sales success becoming the highest volume Z-car for Nissan. To become even more competitive in the sports car market, the second generation 300ZX was driven up-market. It was redesigned to be faster and to feature more advanced technology, but came with a higher price than its predecessor, with consecutive price increases each model year of availability. As such, sales dwindled each year, a trend in the higher end sports car market at the time, and Nissan placed a hiatus on selling new Nissan Z-Cars to the US after the 1996 model year, though the car would continue to be sold in the Japan domestic market until 2001 in low production numbers. Car and Driver placed the Z32 on its Ten Best list for seven consecutive years, each model year of its availability in the United States. Motor Trend awarded it as the 1990 Import Car of the Year. The Nissan 350Z, officially the Z33 generation Z-Car, succeeded the 300ZX in 2003.
