The story
Originally named the 4200 GT, the Uirapuru was developed to showcase and promote the capabilities of Brasinca, who built trucks and stamped car parts for other manufacturers. 77 cars were made from 1964 to 1966, including three convertibles, when Brasinca shut it down due to high manufacturing costs.
The Uirapuru bears a strong resemblance to the Jensen Interceptor, which entered production the same year that Uirapuru production ended, and took styling cues from the Uirapuru.
