(97 km/h) took 8 seconds flat and the car could reach a top speed of , making it the fastest street Manta ever built. If not for the big 1980s fuel crisis being at its worst at that time, several are sure that Opel would have adapted the idea and built a series of 6-cylinder Mantas. But instead they chose to build the economically more affordable Manta B with a 1.8-litre alloy head OHC style engine in 1985. Convertible versions Vauxhall, from 1978 until 1979, offered the Cavalier Coupe in convertible format called the Centaur. Only 118 of these were made and fewer than thirty are believed to survive as of 2007. About a quarter of these conversions were built using a Manta, rather than Vauxhall basis. The cars were developed by Magraw Engineering and sold through Vauxhall dealerships on behalf of Crayford Engineering.
