The Coupés from the midsize series (from front to back) are the Coupés from the W124 series (1987 to 1996), W123 series (1976 to 1985) and W114 series (1968 to 1976)
Personal note: growing up in New Zealand some friends of my parents had a W114 250CE which, as a child, I thought was very special indeed. They had a bad accident in it but a tribute to Mercedes safety engineering, they walked away with a few bruises though the car was damaged beyond repair. They replaced it with a Series 3 Jaguar XJ6
Audi A8 Coupe Concept, 1997. Audi contracted IVM Automotive of Munich, Germany to build a two-door Audi A8 Coupé and was considering production of the vehicle. It was displayed at the Geneva Motor Show. Ultimately, Audi decided not to put the A8 Coupé into production, citing lower-than-expected sales figures for the similar BMW 8 Series and Mercedes-Benz S-Class Coupé. Only one A8 Coupé was ever built
Honda (Acura) Legend Coupe, second generation, 1990-95. The second generation Legend had a longitudinally mounted V6 as opposed to the first generation’s transverse V6. The KA7/KA8 series Legend was the last generation to include a coupe version.
Nissan Figaro, 1991. A limited edition retro-style coupe based on the Micra, the Figaro was sold only in Japan though many have subsequently been exported. Another product of Nissan’s Pike Factory, demand for the cars was so great that prospective owners had to enter a lottery to win the right to buy one. Originally 8000 cars were made but a further 12,000 were added to production numbers.
Nissan NX Coupe, 1990. The NX coupe replace the less conventional EXA and was revealed in prototype form at the 1989 Tokyo Motor Show (yellow car). The car featured a T-roof with removable panels (it was also available as a hardtop).
