YourMechanic is an on-demand car repair service, offering more than 500 repair, maintenance, and diagnostic services. These mechanics can travel to your office, or yes, they even make house calls. Available in the top 50 largest U.S. metropolitan areas and beyond, users can go online or to the company’s mobile app to get an upfront quote for services ranging from basic maintenance—oil, brake pad and spark plug changes—to more complicated diagnostics and repair. Before scheduling an appointment, the customer can read ratings and reviews of the mechanic. The flat-rate quote doesn’t change, the company says, even if the job takes longer than anticipated.
