I went from this Limited with OEM sport hood:
to this:
-GX rides much smoother and quieter and this is likely a testament to all the work Lexus put in to shield you from road noise (thicker windows, covers, insulation) which adds up to lbs
-GX has many more auto features that I enjoy like instant ride control (which I use more often than I thought), auto height, auto lights, auto wipers, rear climate, auto windows all four, etc. It even has lumbar for the passenger.
-The 4R holds its value better because I think people are scared of the more complex air bits and the lack of aftermarket support. I'm sure the brand marketing has something to do with it. We know better, but the GX in and of itself is a young buck in the line-up compared to the multi-gen 4R.
-Seating comfort is identical (short on thigh support), but I love the reclining rear seats on the GX. The third row is also more useable due to the greater interior height. The 4R has a sportier look on the outside with its chopped off roofline, but I've always admired the GX's perfect greenhouse proportions - it pulls it off much better than the Merc GL and LRover Disco (which both are tough to grow old with due to high labor/parts costs and substandard engineering relative to Made in Japan). My fav angle is doggy.
-I love that I can easily get a genuine Philips 4300K bulb matched to the existing headlight unit at a low cost. I don't like to retrofit and do all that backyard garage stuff.
My wife drives a 2011 Range Rover Supercharged and I simply don't trust it like I do the GX which is essentially a Land Cruiser. The Rover is the super model, but its beauty fizzles out right quick to the GX's slow burn. 2UZ-FE is a gem along with that transmission - built to last.
