Welcome to the world of high-stakes tuning and street racing! Welcome to Underground Garage! It's your playground where you can unleash your creativity and mechanical prowess. Fix cars, tune them up, and hit the road to test their build to the limit. Start out by doing jobs for customers, mechanic work, and making a name for yourself in the scene by racing through the night. Then, when the time comes, build and expand your own underground garage.
Every car is a masterpiece waiting to be tuned and modified. Enjoy 20 different authentic and finely detailed cars, including sports cars, sedans, compacts, and muscle cars. Master mechanics where every change matters and impacts how your cars handle on the street. Each car is built from dozens of parts and features realistic collision damage to the engine and body. Rotate, disassemble, and reassemble thousands of different styles and interactive parts to fill customer orders or to build the car of your dreams.
From spoilers to neon lights, everything is available for customization. Leave your personal touch on the cars you work on and stand out in style with a wide range of stickers, colors, and decals. Experience the zen of authentic simulation as you bring cars to life with precision and care. Experiencing power trouble? Test the battery and repair or replace it if needed. And don't forget to check the oil, fuel, coolant, and brake fluid before you hit the road.…
