I can’t speak to Piedmont NC… but I would suspect that any market within a 75 mile flat bed delivery radius of 1M people will survive…but to prosper (imho) requires the Entreprenuer to having a skill set to communicate inherent costs to repairing these cars to clients and maintain a relationship through it all. Further, I think you’d need a or business model that has multiple income channels because one guy wrenching to support a shop will be a difficult way to make a living. Case in point….when I was troubleshooting my reverse lights not working, I remember thinking to myself “how could you justify 3hours (@$110+/ hour) to some poor bugger to fix this?”or worst yet, another project I had in getting the fan motor working which would have been 8 ugly hours and some rusted parts that would take you a day to track down….and the customer getting a bill for $1500.00 - when he expected $150.
Unless you have a lifelong desire to have your own shop -which is on to its own enough reason for sure - be prepared to stock/ sell parts, refurbished cars…get a cool logo and sell some swag…host cars and coffee to become well known In the community- anything over and above wrenching. After you hire a second guy to work a second bay, then somebody to do the books, clean your facility once a week, property taxes..on and on..you may wish you’d spoken to your existing shop and work out a deal where you are paid wage premium for your unique skill set or ‘book rate’ for a given tasks..even commission on parts you install and become “the guy” all then enthusiasts request to fix their cars given your knowledge . Anecdotal evidence, but I get the sense guys on FAQ2002 are by and large knowledgeable and sensible and not your average customer because most folks don’t understand -nor want to understand (and pay) - for the time it takes to do this work…
