There were/are more than one Intermeccanica.
Automobili Intermeccanica and Intermeccanica International.
This looks to be an Automobili Intermeccanica built on a VW pan. You can tell by the Intermeccanica stamp on the hatch hinge. The manufacturing process was sold to CMC/FiberFab in the early 80s.
Intermeccanica International, currently builds tube framed cars.
