Mangustas were unusual in many ways and one is the fact that the official factory designation was 'Tipo Mangusta' instead of 'Tipo' and a number like all other DeTomasos.
I've only seen a few with the 'tipo' plate, and on a '70 car for sale a few years back, the 'tipo' plate was stamped with the 8MA serial number.
