That seems important. I'll make sure to keep it in mind. What can you tell me if i have an issue with the so-called Lemon Law?
Then you can refer to Lemon Law section to see what  you can do about it, to resolve your problem.
Look, this is totally hypothetical, but lets say i file a complaint. What happens if i'm given the reason?
If that happens, then DMV will enter the case with full force, taking actions against the shop. Possible consequences may go from suspension up to license revoking and even fines. These includes possible restitution of any money you lost with them.
