Posts stay forever.
However, keep in mind that entire topics often get moved - for example, topics that are not directly NSX-related get moved to the Off-Topic forum, topics relating to particular geographical areas get moved to the corresponding forum, etc.
Individual posts that don't conform to NSXprime prohibitions (against personal attacks, non-NSX cars for sale, etc) may get deleted by the administrator (Lud).
Are the two posts that you claim were deleted, the topics entitled "Value on '95 Red ???" and "95' Red 12k for 43k. Yes or No???"? If so, those topics were moved from this General Discussion forum to the forum called "New & Prospective Owners / Car History / Comparisons", and they are still accessible there (
here and
here).
One quirk of the UBB software is that, when you do a search, it only links you to the URL (website address) where it was originally posted. When the topic is moved to a different forum, it appears as though the search link points to a web page that no longer exists, when in fact it still exists but you can't use the search function to find it (much to the consternation of the Forums Nazi, I bet
).
