My best friend lives in phoenix and takes his z06's and vipers to a local place with a rented lift to do all his work. This is where I got the idea.
The shop would have air and air tools, speciality tools to rent and wheel and tire eventually. The business model would be set up as strictly a rentable shop by then hour. Not selling cars. Not advertised to public as a garage etc. If a local mechanic wanted to run his business out of there so be it. The main source of Mo eyes would be renting lift and tool rental.
My dance studio rents the ballroom to teachers per 45 mins. This same principal would apply to lifts.
My attorney would create a waiver liability form everyone would sign basically taking risk from me to whoever is working. That's a given.
I do like the country try club but for cars idea. A membership
