Saw a 2004 GX at Beverly Hillls Lexus. Car is the same as 2003 model. Looked under rear of car at the suspension and it was the sane as the 2003 next to it. The brochure says the Kinetic is to arrive around November. Sounds kind of like an off road type of thing.I forgot to check the gvw. In California it doesn't matter anyway. What you save with the feds the state gets. I am sure there are some minor differences that I missed, but it was late and dark out. These are very nice cars or trucks. Skip
