Which model car was driven and featured in the movie "Ferris Bueller's Day Off"?

The story behind this is rather interesting too. The company who made the replica, Modena Spyder California, was brought to director John Hughes’ attention following a magazine spread, and he promptly called in entrepreneurs Neil Glassmoyer and Mark Goyett into his office - replica in tow - for a look. As Neil recalls: “This scruffy-looking fellow came out of the building, began looking the car over and then looked up at a window and shouted ‘this is it!’” Turns out the scruffy-looking fellow was Hughes, and his deliberation over the 250 GT replica or a Porsche 911 Turbo was immediately resolved.
