The Chevrolet De Ville was based on the Constantia but with a more luxurious interior and trim, as well as being fitted with a larger 5.7l engine. The AQ series Constantia was introduced in 1972 and was based on another Australian design, the Statesman HQ. Again, frontal styling was different from the Australian model, this time featuring a unique grille based on the 1970 Chevrolet Malibu.
