high mileage GLE580's
What kind of miles are people running up to in their GLE580's? I just traded up from a 2015 ML400 that I ran up to 150k miles, before selling it and my new to me 2020 GLE 580 only has 42k miles on it and came with CPO for a year. I'm planning on going to a fidelity platinum service contract to mitigate repair costs. The one owner GLE 580 that I purchased came with a 110k mile pre paid service so I should save some money there.

62k on a 2020, nothing major to report.
At 45k an engine mount needed replacement (this requires an alignment afterwards).
58k or so, low pressure fuel line clamp loosened and there was a tiny bit of fuel weep that resulted in a periodic odor. Resolved by refitting it.
Keep an eye on the oil separators for blockage, replace the coolant reservoir every 5 years (silica pack inside breaks down and beads clog heater core), stay on top of specified maintenance (plugs, transmission, diff, 5k oil) and you shouldn't have much to be concerned about. In the S-Class world, there are many high mileage M176s (and 9g transmission) examples with no major fail points to note.
