People are too busy to take their car to a dealership for service. They want convenience, and they are willing to pay a premium for it. Being a self-employed mobile mechanic fills that need and can provide you with substantial additional income—if you know how to navigate the modern automotive landscape.

Originally published in 2010, this guide has been completely rewritten and greatly expanded to address the massive changes in the auto industry. The "old school" methods of cash payments and basic hand tools don't cut it anymore. To succeed today, you need to be a high-tech mobile concierge.
