I, sort of, had that feeling as well with JX being in it's first year of production. But, I had owned a 2004 Lexus GX470, and a 2007 Lexus GX 470, and the only difference I noticed were cheaper materials being used in the 2007 so Lexus could pad the profit margin.... Also, there was a known issue with the drive axle in the GX that started in 2003 and was never corrected despite multiple TSB's issued. Even the 2009 models (the last year the GX470 was produced) still exhibit the same problem which requires you to bring it to Lexus and have them modify the axle....
