Uncle Buck drove a 1976 Mercury Marquis Brougham, a massive, boxy sedan that became an iconic part of his character in the 1989 film. This car wasn't just transportation; it was a visual gag that perfectly matched John Candy's larger-than-life persona. The Marquis was a quintessential "land yacht," a type of full-size American car known for its vast dimensions, soft ride, and powerful V8 engine.
The specific model, a 1976 Brougham, was near the end of its production cycle. Under the hood was a 7.5-liter (460 cubic inch) V8 engine, an engine known more for its torque than its speed, which suited the car's leisurely character. The most memorable feature in the film was its unique horn, which blasted a comical "La Cucaracha" tune instead of a standard beep. This detail added to the car's quirky, unforgettable personality.
Beyond the comedy, the Marquis served a practical purpose in the plot. Its enormous size allowed for scenes like Buck stuffing a massive number of pancakes into the glove compartment and later using the giant trunk to hold his equally giant golf bag. The car’s worn, slightly shabby appearance contrasted with the more modern, suburban vehicles in the film, visually reinforcing Buck's role as the unconventional, chaotic, but ultimately big-hearted uncle.
