has any sort of agreement, formal or informal or otherwise, already been cut by the seller and the dealer?
if not, if you just know they'll be coming on the market and you want to get to them before the dealer does, then no, there's nothing unethical about that. that's just being fast(er).
if yes, if the dealer and seller have already been in contact and have some sort of understanding, well that's a different matter altogether.
your question implies the dealer does not actually physically "have" them yet. but if an arrangement has been negotiated between the 2 of them, then it's as good as if he did. probably not unethical strictly speaking but not the kind of thing that makes friends.
