Assuming that the car was stolen prior to delivery to abc motors and without the knowledge of any representative of abc motors, what kind of title did abc motors have?

I believe in this case that ABC motors is the customer and the car was still being delivered to their office. Therefore the correct answer to this is:

The title of ABC motors would be "Void"

This is considered right away as Void since there was no information or any knowledge on the part of ABC motors about the stolen car.
