This model was released in Australia in 1970 , along with the Mk2 PI, as the replacement for the Mk1 model. The 2000 models shared an identical body with the PI model , but featured chrome bezels on the instruments, and a 3-person rear seat. Most of them were manuals. The engine used a GT6 spec camshaft and a pair of 1.5" SU or Stromberg carburettors, depending on the year.
