BrickEconomy Member Review
“The 2025 Knight Bus set delivers a faithful recreation of the iconic three-story purple vehicle from Harry Potter and the Prisoner of Azkaban. It features improved accessibility with removable floors and roof sections, and includes thoughtful details like a bed and hanging light. The set comes with Harry Potter, Stan Shunpike, Ernie Prang, a sleeping witch, and Padfoot. While slightly shorter than the 2019 version, it offers a good build.”
Brick Fanatics
“As well as some familiar stickered elements that resemble those of 2019’s 75957 The Knight Bus, the three-level vehicle has three beds, which is as many as 4755 Knight Bus from 2004 but with the additional details that come with 20 years of advanced elements and building... More techniques. While the beds are not next to one another on the bottom floor, this makes the 2025 set by far the most accurate Knight Bus model to date and with the most minifigures of any previous build to boot.”
