It is unlawful for any person or his agent to disconnect, reset, or alter the odometer of any motor vehicle with the intent to change the number of miles indicated thereon. Whenever evidence shall be presented in any court of the fact that an odometer has been reset or altered to change the number of miles indicated thereon, it shall be prima facie evidence in any court in the State of North Carolina that the resetting or alteration was made by the person, firm or corporation who held title or by law was required to hold title to the vehicle in which the reset or altered odometer was installed at the time of such resetting or alteration or if such person has more than 20 employees and has specifically and in writing delegated responsibility for the motor vehicle to an agent, that the resetting or alteration was made by the agent.
