There are about 12 dive-able WWII wrecks in Coron (Busuanga). One wrecks has a Jeep and a couple of other vehicles on the inner deck. I stayed at Sea Dive it was reasonably priced and the dive guides were great. The depth of the wrecks was from 25-40 meters. Visibility was not so great but still an adventure.
could be what the OP was asking about then.... yeah coron is some good diving, as is subic bay for wrecks.
I haven't went through all the old posts in the diving section but I'm sure there are some there. It all looks the same to me though, once you've seen a picture of coral you have seen all pictures of coral. They have to be some of the most boring lifeforms to look at. They just sit there....looking a whole lot like plants. I would be much more interested in shipwrecks though. At least there is a story there and you can see the history.
