Hey everyone, don't let this deginerate in a flame war, it really isn't worth it.
Deathrat, in answer to your question, you've got me as to why GM didn't list the full SSEi specs in some of them.
willwren, if you want to do a timeline, I suggest erring on the safe side and listing SE, SLE, SSE, and SSEi all as models from 1992 to 1999 (except no SLEs in 1992). A car site like http://www.carprices.net
will not always be accurate. If you are in doubt over a specific model being available a specific year, a simple Google should clear it up.
