Morris Cowley FlatnoseThe Morris Cowley Bullnose first appeared in 1915, and was known for its prominent bull-like grille. By the 1920s, it had become one of the most popular cars in the UK , and the Flatnose, featuring a more understated grille, came onto the scene in 1926. It makes sense to see one pop up in "All Creatures Great and Small" eventually — and the Morris Cowley in the show was actually owned by Tristan. In one scene early in the series, Tristan (loudly) pulls up in his Cowley and lets out a classic "ahooga" honk, declaring he purchased the vehicle with his "meager wages" as part of his character's continued growth — despite being known as a bit of a troublemaker. In the show, Tristan calls the car "solid as a tractor" and "a beauty," but the other characters are a bit skeptical of the loud and clunky vehicle, passing on taking a ride in the car. Tristan is proud of the car, however, using it to do home visits around town. In real life, it was a different story – Actor Callum Woodhouse, who plays Tristan Farnon on the show, admitted that the Morris Cowley was incredibly tough to drive. He told PBS that the car could only be stopped by pulling back a handbrake "roughly around a minute" before he wanted the car to stop.1933 Vauxhall 14 hp Light Six DeluxeActor Nicholas Ralph plays relatively new veterinarian James Herriot who's hoping to fit in with the vet crew in Yorkshire. By running the license plate spotted in some scenes through the U.K.'s Driver and Vehicle Licensing Agency's Vehicle Enquiry Service, we learn that James drives a 1933 Vauxhall with a 1701cc engine — which means it can only be the Light Six. Woodhouse called the model used on the show "battered-up" and "old" in his PBS interview. He admitted that the car was pretty tough to drive compared to other cars on set. A sharp-eyed fan noticed that the car was having issues in Season 3 Episode 4, including a cloud of smoke coming out the back — but the car reappeared in Episode 6. This model Vauxhall was a success with drivers of the time, reaching 26,000 sales in a year. This is probably because this model was cheaper than its competitors when it was released. It featured a 1.8-liter six-cylinder engine that produced 34 horsepower.
