Generally speaking the early models or so called ‘Pre A 356′ models are more desirable than the later models. At the top of the pyramid and the most exclusive is the Carrera version which carries the legendary 4 cam ‘Fuhrman’ engine. But just below that comes the ‘Super’ speedster. The ‘super’ version had more horsepower (75 vs the standard 60) and the powerful ‘type 528 engine’ for the 1500 Super version.
