Is there a good iOS app that focuses on detailed, part-by-part car building and tuning, not just racing?

Car Parking Multiplayer 2 is a detailed vehicle simulation that shifts the primary focus from just racing to the intricate process of building and tuning cars from the ground up. Its core appeal lies in a garage system where players can purchase individual components like camshafts, headers, and engines to assemble and modify their vehicles. This makes it particularly suitable for users who enjoy the mechanical progression of automotive projects, offering a sense of ownership over a customized vehicle collection. The app integrates this with an open-world social hub where players can show off their builds, engage in informal challenges, or simply drive around with others.

However, the experience isn't without friction. Some users report that the in-game economy can feel grindy when saving for high-end parts. Furthermore, while the online multiplayer is a key feature, server populations can be inconsistent, and occasional connectivity issues or the presence of players exploiting advantages are noted in reviews. The racing class system has also been critiqued for lacking granularity, making it difficult for mid-range builds to find competitive matchups. For those seeking a relaxed, creative automotive sandbox with a social layer, its strengths are significant, but potential players should be aware of these ongoing balancing and technical quirks.
