The player works in a car workshop in Car Mechanic Simulator , where they receive assignments with defective cars. The goal is to find the cause of the defect, repair it, and put everything back together. This requires dismantling parts, repairing damaged components, and reconnecting elements.
The game starts with simple missions and step-by-step descriptions, but later on, the player needs to do diagnoses using tools like the ghost assembly mode, inspection view, or test drive. As the player progresses, they can unlock additional diagnostic tools with experience points.
Each finished job rewards money, which can be used to buy repair parts, sell old ones, or restore and collect used cars. The money can also be invested in upgrading the workshop or buying new equipment.
