TexasRover3, I totally understand your frustration and your move to Toyota. I considered the LandRover or Lexus equivalent. I had a Toyota FJ that I put about 10K of goodies into and had a diff ring gear tooth that broke and left us stranded in Moab. I known defect eventually covered by Toyota. The only car my wife shed a tear over when we sold it.
I replaced that with an old LR4 (same platform as the pre '14 RRS) which I have been able to fix myself as things went south (160K miles on it now).
I just got my RRS SC, and my hope is that I can do most repairs and maintenance myself, but I realize this is a riskier proposition. The RRS checked every box so it's a risk I'm willing to take for now.
I totally appreciate your decision, and sorry RR did not work out better for you.
