What's your starting budget?

  1. Check the licensing for auto repair work

    Many states register or license auto repair facilities and regulate how estimates and warranties work. Mobile mechanics face fewer facility rules but the same consumer-protection laws. This is the part that varies most by state — some require a state license or registration before you can advertise, others leave it to the city or county. Confirm both your state board and your local government before you take a job.

  2. Decide what the business needs to open

    General automotive maintenance and repair from a shop or mobile mechanic setup. The setup areas that usually matter for an auto repair business: State auto repair facility registration, ASE certifications, EPA/hazardous-waste handling, Shop lease + lift, Estimating and warranty policy. Typical cost to get operational: $10,000–$75,000 (mobile setup to a full shop with lifts).

  3. Pick a structure — sole proprietor or LLC

    You can start as a sole proprietor with no filing, or form an LLC (usually $50–$300 depending on your state) for liability protection. For hands-on trade work where something can go wrong on a customer's property, most owners choose the LLC.

  5. Register for state taxes and get insurance

    Register with your state's tax agency if you'll collect sales tax, then line up general liability insurance — most contracts and license boards require proof of coverage.

  6. What auto repair businesses charge

    Labor at a posted hourly rate ($90–$160) times book time, plus parts at a standard markup. Diagnostic fee $80–$150. Mobile mechanics charge a premium for coming to the customer. Non-discretionary and steady — cars break regardless of the economy, and people keep older cars longer in a downturn. Fleet accounts (contractors, delivery, rental) add predictable volume.

  7. Get your first auto repair customers

    Google + reviews, being the honest shop in local Facebook groups, and fleet outreach. Trust is the barrier — transparent estimates, photos of the problem, and warranties win repeat customers. Fleet accounts add stable volume.

  8. The mistake most first-year auto repair owners make

    Competing with the dealer and the chains on brand instead of on trust. The winning position is 'the honest local shop' — photo the worn part, explain the options, warranty the work, and the repeat business and reviews follow.
