It is probably an SE Sport. The same car I used to have. I don't know that LX even existed in 1999.

It was a good car although I began to hate the automatic once I started to be more concerned performance/fun wise.
The price seems a little steep to me but I don't know how that goes in your area.
If you think a 5 speed could work for you, you may want to check out the SVT version or even a 5 speed non-SVT. That is where the fun is.
Good luck and welcome to the world famous CEG!
