Bruce Schreiner's unrestored original 1970 Boss 429 was recently acquired from an estate sale. The car had been in storage for more than 41 years, and Bruce had been after it for the past 15 years. Kevin Marti has confirmed that this car is the one and only Boss 429 that came from the factory with rear spoiler and sport slats. The car sports original paint, interior, and front tires.

Completely unmolested, this Boss 429 is all original straight down to the Goodyear rubber. All of the documentation, elite Marti Report, and Ford Motor Company stickers were included and still intact as it slept for four decades in an old, windowless garage collecting dirt and dust in every crease and crevice.
