I am not in this line of work but did own my own auto repair shop for 15 years so I do have some experience
As long as you have all the legal angles covered, I say just give it a try one time how you think it would work best for you
If it does not work, then you know. either change the arrangement or dont do it anymore.
If it does work, great
Sometimes you just gotta take a chance
