Please provide any assistance you have for the following question I encountered taking the Ch.3 Quiz:

John is allowed use of a company car; what endorsement should he add to the PAP?

A. Extended Non-Owned Coverage  Correct

B. Towing and Labor  Incorrect

C. Joint Ownership Coverage  Incorrect

D. Named Non-Owner Coverage  Incorrect

I based my answer on the following information given through the course:    (I incorrectly chose Ans. D)

3.11 Endorsements:  (From Sect. 4 of Unit 3)

Most of the common endorsements used in the personal auto policy are listed in the study manual.

Extended Non-Owned Coverage: This endorsement provides coverage for liability and optionally, medical payments for a named insured or family member who uses a company vehicle. The individual covered must be named on the endorsement. This endorsement is used when an employee in allowed use of the company vehicle.

3.11 Endorsements:

Named Non-Owner coverage: This endorsement provides Liability, Medical Payments, and Uninsured Motorist coverage for a named individual who does not own an automobile. This endorsement maybe used if an employee uses a company car and does not own a vehicle.

These two endorsements seem almost the same (see underlined portions). Especially when trying to remember so much info.  :)

The main difference I see is that Extended Non-Owned Coverage offers to cover a family member using the vehicle (why for a company car I don't know and therefore did not choose).  Is there some main point that I should remember when comparing these two plans?  Additionally, the study manual descriptions (pgs. 61-62) do not mention "company car/vehicle" at all.

Thanks for your help!
