What year and make is the Porsche in "Scarface"?

Its a 1983 white porsche 928. Theyre 4.6L v8 front engined porsches. They were the most expensive at the time, but more of a GT car than a sports car (like the 911s). They are seriously cool, and pretty inexpensive, but outrageous to maintain. Service and parts on them are simply rediculous.
