I somewhat don't agree, 80% is amazing material, and 20% is super cheap plastic. What's the point of putting in over the top quality materials to ruin it with some cheapie stuff like the center speaker cover (major source of noise) and the radio. Now I'm not going to say LR sucks because of this, I love mine, and had some high end BMWs in the past that were crazy noisy, but if LR just got rid of, or used a little more felt, or attention to softening the clips where there is cheap plastic, the LR4 would be a Rolls.
I agree the build quality and materials used is top notch - especially compared to the older Disco's. I did notice the plastic inside of the center console box was cheap and thin, but it is just the inside of a box.
