2-door/4-door saloon/hatchback/estate car.
Draw a deep breath before working this one out - Chevette was a Viva engine/gearbox transplant to an Opel Kadett floorpan, but with unique nose style and (until 1976-model Kadett City arrived) special hatchback tail. Torque tube back axle layout, also like the Kadett. Not a direct replacement for the Viva HC, but gradually took over, with saloon and estate car types arriving in mid-1976. All UK cars with the same power train, sturdy but unexciting behaviour, and surprising 90mph top speed allied to 35mpg economy. A successful car for Vauxhall, which also gave rise to the rally-winning Chevette HS.
