Ahh... Im asking my self the same question trying to sell my rav4. I think the 'L' stands for "long wheel base" Im not to sure what the 'J' stands for though. The L is for Limited meaning top of the line with PWR moonroof and mirrors, etc. It is the "trim level". The S is for "Sport" which in the 2004 model year has a non-functional hood scoop. J seems to be the right hand drive Japanese version if its a generation 2 Rav before the 2003 model year I believe. Hope this helps.
IT MEANS LIMITED EDITION
