Ok just got back from Overland Expo 2013 and did the obstacle course in both my LC200... and immediately afterwards in the brand new 2013 Range Rover. Couple thoughts:
1. The new RR is nice... as in very nice (fit, finish, styling, etc.)
2. The new RR went through the obstacle course cleanly, and cruised through a spot that I saw even a nicely equipped Defender get stuck in
3. The new RR's interior is awesome... maybe too nice
4. My LC200 did the course a little more easily
I was lucky enough to take the driving course with a former Range Rover Camel Team leader (had to have a RR driver with us even in our own vehicle) and he commented repeatedly on how well built (solid) the LC200 felt, how smooth it was over the bumps and how he was surprised that so few were sold in the US.
Soooooo here is my perspective. Firstly, of the thousands of attendees at OX 2013 I don't think I saw anything from Land Rover but Discovery I-II's and LR3-4's. Certainly no Range Rovers that were 2008+. I think it ultimately depends on what you are going to use your vehicle for. If you want a luxurious daily driver that can take you skiing and on long road trips to the golf course get the RR. If you want to do the same (in less style) but be able to go anywhere in bullet proof confidence (minus rock crawling or narrow trails) pick the LC200. Lastly, modding is part of the whole 4x4 experience for me. There is a very large and growing aftermarket parts market for the LC200, which will continue to grow as these vehicles come off of lease. Pick a basically new LC200 with 70,000 miles on it for around 45K and add 10-15K in mods and be confident you will have a bullet proof truck for another 200K... or buy a Range Rover and do you best to unload it before its original 50K warranty expires. = D
