Biff has totally seen the DeLorean several times. He sees it at the end of the first film, which consequently is the beginning of the second film. He sees it again as an old man, which is enough for him to connect the dots and figure out it's a time machine (Old Biff displays a level of deductive reasoning that is as paradoxical as time travel itself), leading directly to him stealing the DeLorean and enacting his evil plan. And he sees it again at the end of the second film, as a teenager back in 1955, when Marty steals the almanac back while riding on a hoverboard and the DeLorean lifts him to safety.
This particular timeline of Biff's is never corrected. After Marty and Doc come back from the Old West, Marty finds Jennifer back on the porch where he left her, meaning that everything that happened before he put her there still happened -- Biff saw the DeLorean take off after waxing George McFly's car, and he saw Marty, as Calvin Klein, steal his future book and get towed to safety by a Jetsons car.
"I really hope I'm just hallucinating from the manure fumes."
What are the odds that this shit stuck with Biff, at least enough to come rushing back when he sees Marty and Doc gaily take off for another adventure as he stands staring, wearing only a green tracksuit and his own muddled confusion?
"... I think my mind is haunted."
When the series ends, the time machine is destroyed and the future is safe for Marty and his family, but all of this crazy bullshit still happened to Biff. How long will it take him to realize that it wasn't fate that screwed him over time and time again once Marty shows back up at the house dressed like a cowboy?
"Hey, Marty! I can't see anything but knives when I close my eyes!"
