Final answer:
False Pretense Coverage (option 1) is the garage-keepers policy endorsement that protects against the theft of a vehicle during a fake test-drive. This coverage is specific to the act of a vehicle being stolen under the guise of legitimate interest or intention to purchase.
Step-by-step explanation:
The endorsement to a garage-keepers policy that would cover the theft of a vehicle by someone who was pretending to take it for a test-drive is the False Pretense Coverage. This specific type of coverage is designed to protect a business from losses incurred when a vehicle is stolen under false pretenses, such as by someone pretending to be a legitimate customer taking a vehicle for a test drive.
It is important to note that this type of coverage is separate and distinct from the other options listed, such as Drive Other Car Coverage, which typically provides coverage to individuals driving a car not owned by them; Garagekeepers Legal Liability Coverage, which generally covers damages to customers' vehicles while they are in the care of the garage; and Hired Auto Coverage, which is intended for vehicles that are leased, hired, rented, or borrowed by the business.
