Cool collection and location!
Is this the silver one in Idaho?
Seems there were 2 low mileage vehicles located in the same area (probably second home vehicles) that someone else also posted. One of the two had some damage to a wiring harness and required a replacement according to Toyota history, you may check that out.
As far as a good deal or right decision, it largely comes down to your satisfaction and future plans of usage.
Opinion, if you are buying it to drive, I would not pay a big premium for an extremely low mileage rig, it will just be another 100k mile Land Cruiser in several years and you lost the premium you paid.
If you are adding to a collection and plan to drive it just a few thousand miles per year, it is a different story.
What are the other comparisons for ~$50k?
Good luck, keep us posted!
