Are OEM car accessories the same as Genuine accessories?
 

I am about to buy a trunk tray and all-season floor mats from a seller on eBay. As they state that the accessories are OEM, but they are Honda dealership, I have no idea what the difference between what the difference between genuine and OEM they offer. The price is almost half off. Would it be worth buying the OEM ones if they are not exact the same as the genuine ones?

OEM stands for Original Equipment Manufacturer. They would be what came on or as an option for the vehicle from the dealer.

OEM means original equipment manufacturer. I am not sure if it is the same for cars, but for computer parts it is the same as the manufacture items. The just come with less packaging and are a lot cheaper.
