Only rent this if you are a diehard fan of the early 70s movies otherwise stay away. There are loads of cute girls but two things killed it. The camera work is awful in nearly every hardcore scene, it shakes too much and does not sustain any action, bouncing all over the place, I can't tell one person from another. None of the guys belong in porn if you know what I mean and most appear in all three movies. The last movie, Grand Prix, was ok and has the best girls of the three titles.
