The Purvis Eureka is a sports car which was produced by Purvis Cars at Dandenong in Victoria, Australia from 1974 to 1991.

First exhibited at the 1974 Melbourne International Motor Show, the Eureka was based on the British Nova kit car design of 1971. It utilised a Volkswagen Beetle chassis, a fibreglass body and, most commonly, an air-cooled Volkswagen flat four or a Ford inline four-cylinder engine. Others with Mazda Rotary powerplants were also produced. The Eureka was offered both as a kit car and as a fully assembled vehicle. The coupe body had no doors, access being via a manually operated one piece canopy, although a power operated canopy was later offered as an option. A Targa top version was also available from the early 1980s.

Three models of the Eureka were produced.

  • Purvis Eureka Sports, from 1974 to 1975
  • Purvis Eureka PL30, from 1975 to 1976
  • Purvis Eureka F4, from 1976 to 1991

235 examples of the Eureka Sports were produced and the total output of all Eureka models had reached 683 when production ended in 1991.
