We have worked with the car part industry in the past, and they all received the parts information, images, etc. from the companies they ordered from.
It has been the same for other industries as well, the information about the products they can sell is provided by the companies they order from.
Looking at this from the perspective of using your data, the big problem I see is, where can I order the part from? I.e., if I populate my store with your car parts data, where can I get the part if a customer orders it?
