I wouldn't think too hard about this one. Yeah - a dealer told us that IS stands for "Invididual Sedan", but what difference does it make?
I like to think of IS300 being
"Inline Six, 3.00 liters displacement".
The RX/LX probably have the "X" from "4X4" (offroad)
I am sure some marketing people ponder these things over and over and probably pick letters based on how they look in print and what psycology studies say about peoples' impressions of certain letters.
Well, Bernie Kitts from Lexus of Rockville told me it meant "Individual Sedan"... So who is right? Who cares? That is why I said not to think too hard. I think people assign words to the "IS" arbitrarily to suit their fancy.
