If you like Car Mechanic Simulator, there are plenty of other similar games. Among the closest (and equally as highly regarded) games to Car Mechanic Simulator 2018 is My Summer Car. It's not necessarily as realistic, but there's certainly a lot of humor and fun to be had. This is especially in regards to exploring its vast world, and interacting with other characters. There's also another mechanic simulator-type game coming up, called Underground Garage. It's yet to be released but could come sometime in 2022. From the teasers and what we know about it, Underground Garage covers all aspects of street racing. These include the actual racing part, as well as repairing, tuning, and testing those cars.
