Audi A4

This Audi A4 Quattro is unique, and, as Akīchirō states, has the special AWD feature, that allows them to take the old road in the first place. Although the car from the movie is grey, this color is almost impossible to find in real life. It is said that the engine noises from a real Audi A4 1.8 were used in the making of the film.
