I'd use it for sure. I'm mechanically skilled ( can use tools ) but no idea and not much confidence to do much to the car that isn't basic electronics.
It'd be even better if you had skilled mechanics on hand to guide / bail out n00bs like me with advice and pointers.
You might even be able to hook up with insurance companies and high schools to teach the basics of safety maintenance ( change a tyre safely, check pressures and fluids etc... ) - there is some instant business for you with a low cost-of-sale.
If you need business help try SBMS small business mentoring services - they'll help you run the numbers, build the business plan etc and they're cheap.
Your main issues will be young people doing stupid things in cars, tool theft/damage, insurance and after-hours break-in's etc. nothing that's a show stopper but just things you need to consider.
Good luck, hope you open a few across the country and make some $$!
