Just purchased my new-to-me 2008 LX570 after initially searching for a 2013-2015. The threads on MUD have been more helpful than I can say, so I wanted to contribute back to the community.
While there are many threads on specific mods or services, I searched for a consolidated baseline checklist to follow after buying my rig. My mindset while searching for my LX570 was that mods/service would fall into 3 categories:
1. Must-Do Service (Regardless of year/mileage purchased)
2. Higher Mileage Service (100k+ miles on rig purchased)
3. Best-practice upgrades (100% optional)
I'll include my list below approximate DIY cost.
Please comment with other things you'd add. I'll promise to come back and update the initial post with your recommendations, so we can have a consolidated list.
