I bought t 2006 GX 470 GPS / package audited. Excellent car. X5 drove past 2 years. You can not even compare. Yes, the X5 is not acceleration device a bit better, but compared to the GX just rules. X5 was like driving a tractor. GX journey is so smooth, you really do not want to continue to drive this car. GPS is great, the camera back is very nice.My wife loves it.
