Random side note - this might explain a mess of LCs being listed as FE or 1958s when they're clearly not. When I was searching for FEs there were 1958s listed as FEs that were not, and LC LC listed as 1958 that were not.
In my (limited) experience so far, the insurance agents and Motor Vehicle Branch employees registering your vehicle don’t understand the difference between the 1958, the Land Cruiser and the Land Cruiser premium. They correctly or incorrectly select from drop down boxes in their software which may or may not also be correct. The distinction in the different trim levels eludes them.
I have experienced that with other brands and trim levels as well- one dealership I was trading in a vehicle at offered wholesale value for the lowest trim level and made me “prove it” that my vehicle’s high trim level had a wholesale value twice what they had arrived at in their valuation. I suspect they knew in this case and were just trying to see if their offer was going to fly- it pays to be an informed customer, otherwise the trade in process is practically designed to take advantage of you.
