The question is about "list" price, not so much what price the item cost the vendor, but what the vendor's supplier suggests the part be sold at.
I know the question was in reference to OEM, but If you are using TVH as a vendor and then using their "list price", you really should be doing the math and checking to be sure you are not losing money, when I used to check, I would regularly see places where the "list price" was -less- than what $ we paid.
I usually just consider published -list- prices as a 'suggestion', and we create our own "price books" for our customer's. This is a forever ongoing process, just part of "continual improvement".
What counts most to us is 2 things, what the customer could purchase a like item from a different vendor, and [most important] what we pay for that item.
We HAVE to make a profit on -everything- in order to pay our taxes and keep the doors open.
and I would bet, as far as most OEM dealers, it is something that has to be spoken about in generalities, not specifics.
