[IS300LEX]

I think they'd rather much keep it consistent and just call it the IS300-C. Of course if people took to calling it the IS300 C-type, that would make it sound too much like a Honda. Just out of curiosity I've had the debate over what the E in ES stands for, Executive or Entry level, the only ones Im positive about are SC and LS, not even sure what RX or LX stand for.
