I think d20 Military Vehicles by GoO would completely cover your vehicle needs, but then I am biased (I wrote part of the book) . No feats, PrCs, etc., though, just every military Land, Sea, and Air vehicle we could cram into the book, as accurately as we could describe and stat them out using unclassified data.
