Yeah, that 90 day rule has been there as long as I can remember as well. El Salvador is 60 days IIRC, and Costa Rica is 90 days as well. Not sure about Nicaragua and Panama.
When I was headed north Mario and I crossed into Guatemala and when I was at aduana, the guy told me I could not enter Guatemala with the bike since I had been there in the previous 90 days and cancelled the import permit. However, it had been over a year and half in reality. The SAT stamp in my passport showing that the bike had left Guatemala, did not have a date on it, and there was no record in the guy's computer. Fortunately, I still had the SAT receipt with the date when I left Guatemala a year and a half earlier. After producing that paper, I was permitted to bring the bike in.
