The original Škoda 110 Super Sport was a concept car, with a rear engine and rear-wheel drive. After two years of design work, a prototype was made in 1971, but it never went into mass production. Some 10 years later, the car prototype was modified by graphic Theodor Pištěk for its use in the horror film. He gave the car a black paint job, new front and rear lights, and a distinctive rear spoiler.
