The "mit beschränkter Haftung (mbH)" suffix (German: [ˈɛmbeːˌhaː], "with limited liability") is sometimes added to the name of a firm that already ends in "-gesellschaft" ("company"), e.g., "Mustermann Dental-Handelsgesellschaft mit beschränkter Haftung" ("dental trading company with limited liability"), which would be abbreviated as "Mustermann Dental-Handelsgesellschaft mbH".
You can start an auto repair shop from the comforts of your home if you have a garage and the right tools. On the other hand, if you don't have the space to open a business from home but do have the tools, you could open a mobile auto repair shop where you travel to the location of the vehicle in need of repair. There is also the option to start your own car wash and detailing shop. You don't need to have any mechanic skills, just a keen eye for detail and a love for getting your hands dirty. This is a very rewarding business that can become extremely profitable with the right promotion.
