The DeLorean can go above 88 mph. Can Biff’s 1946 Ford? I doubt it.
On the other hand, if the DeLorean goes too fast, it will disappear in flames, and Biff will be the winner by default.
Somebody please travel back in time and Marvin Berry the shit out of this slot car set so I could have had it in 1985, please. It costs too much now, and I don’t have the floorspace.
