@Seabassjfr, I have a 2013 LR4 5.0 HSE - very similar. I purchased mine with 72,000 miles on it last year for $22K. I did an Autotrader search for 2010-2012 LR4s starting in Seattle but had to widen it to "any distance away" so it looks like these are all 2000 miles from you but it seems in the ballpark that the 150,000 mile ones are around $11-12K.
The service history also looks pretty good - they did the major services (30/60/90/120) all within 1-3K miles of the service date.
So...two owners, roughly $20K/yr, almost complete service history at LR dealers - that's pretty good. The service that concerns me is that 135K major rebuild - I'd want to know what happened there. That looks like a major service (timing belt tensioner, gaskets, seals, valve adjustments, valve guides, head?) - If done well...that's probably a good thing.
I'd go to the dealer that did all the major servicing for customer #1 and see if they'll give you the service records in full detail. But otherwise, seems like a potentially good find.
Also if you can, get it inspected by a really good independent mechanic who knows Land Rovers specifically.
If you do purchase it, as has been discussed to death on this forum elsewhere, I'd budget $1500 to immediately do the coolant crossover pipes (front and rear) and maybe the water pump while you're in there and complete fluid swap. Then get it on a 7500 mile engine oil change regimen and maybe consider sending the oil into Blackstone Labs
https://www.blackstone-labs.com to see what is going on in the engine and keep an eye on things.
Let us know how it goes. I love my 2013 with the V8!
