In 1990, it was the leading racing model for the 500-mile race of Indianapolis. The company Chevrolet announced the appearance of the serial model Beretta in the back of a cabriolet, but it never appeared on the exhibition stands.
The Chevrolet Beretta GTU model was a special version of the Beretta, which was sold from 1988 to 1989. For its creation was taken model Beretta GT (package improvements suspension z51). It was equipped with new 16-inch aluminum rims, rear spoiler, new mirrors, a special trim and stickers on the body.
