Biff 1985

Biff's Auto Detailing was a company run by Biff Tannen, founded in 1980, which did speciality work on cars.

Because Biff had to do everything for himself, and thanks to his aversion to filthy automobiles caused by twice running into a manure truck in his own car in 1955, he would come to the homes of his customers to wash and wax their automobiles. One of his customers was George McFly, who liked two coats of wax on his BMW 733i. The business phone number, listed on the side of his pale yellow truck, which appeared to be a Ford Courier, was 840-3851. Biff also had 'Biff's Auto Detailing' matchbooks printed to give to his customers and advertise the company; he was intending to show one of these to Marty McFly when he witnessed the flying DeLorean departing for 2015.

After Marty destroyed the Grays Sports Almanac in 1955, using a matchbook he had taken from Biff Tannen's Pleasure Paradise Casino & Hotel in 1985A, the text on the matchbook's cover changed before his eyes from PLEASURE PARADISE to AUTO DETAILING. In a kind of poetic justice, Marty had burned the almanac using a matchbook advertising the business empire that this very book had made possible.

It would appear that Biff still ran Biff's Auto Detailing in 2015, as he would wax (two coats, naturally) the hover-converted orange and black BMW 633CSi convertible owned by his grandson Griff.

Behind the scenes

  • Biff's yellow truck is never seen fully on-screen, so it remains unknown as to whether it was a Ford Courier, a Datsun or a similar vehicle.
