Time to look outside your "near me" radius. Not trying to talk you out of an IG, but since you mentioned alternatives...
'17 LC200, 62k, some goofy overland stuff, $58k
'17 LC200, 57k, $67k
'18 LC200, 64k, $64k
Many more LC200's out there....
Also, for G-Wagen's;
'04 G500, 60k, $44k
'04 G55, 52k, $55k
'04 G500, 14k, $60k
After my own heart. Sounds like we owed a similar G500 build.
You probably knew there were updated window regulators, door/seat switches were always finicky. But engine/trans/drivetrain is super solid.
