The ls400 looked the same for damn near 10 years 95 changing the body stlye somewhat but still looked the same too me. The GS looks like it is following these footsteps. I have no problem waiting til 05 or 06 to see the new gs. My 98 gs will be looking just like a 03/04 :) I am willing to bet for the 04 gs they change the tailights to red and clear. I will bet $$$ on it .

Don't forget the SC keeping the same body style from 92-00, minus changes to taillights and bumpers, etc.

I forgot about the sc. You are correct that body style was around for awhile aswell. The es was only around for 4 years.92 to 96 1st gen ,2nd gen 97 to 01 I believe. I think the es changes every 4 or 5 years because of all the cars in its class changing every 4 or 5 years. Look at infinti and acura. They change every 4 or 5 years aswell. This is very interesting if you think about it
