Comparing the new 2017 RRS and the new 2017 Discovery 5 they "seem" similar.
2017 Disco HSE TD6 starts at $58k and the 2017 RSS SE TD6 starts at $67k here in the United States.
Yes the RSS is slightly more expensive but is is also more nicely optioned I believe. I heard the new Disco is based off the RR chassis and even has the same TD6 engine. It seems like the best value for the money. Being "new" to LR, I am trying to research as much as I can about both models. Info on the Disco is scarce as it is still several months away from shipping production units, most are probably customer orders so seeing one on the sales lot may not happen for a long time.
Getting the TD6 is an absolute, I am especially looking at 2 speed transfer case and Terrain Response 2, both optional on the Disco. I currently drive a 2016 Wrangler Rubicon Unlimited. It went off-road the week I took delivery of it. Same will happen with a LR. I am looking to "upgrade" comfort at the loss of some "ability". That's ok with me.
This is a pretty nice forum you all have here.
