GLC 63/M177 Reliability?

[Überlandung Geländewagen]

Hey all,

Been looking for a replacement daily for the other half, and she's been eyeing a 2018 GLC 63 AMG. My hesitation is reliability, the ones we have looked at have 75k miles or less. I've heard the M177 are reasonably reliable as long as you stay on top of the maintenance, but I'm not sure about the rest of the car. Any two cents from owners or mechanics would be greatly appreciated. We've had our share of newer Benz SUVs but never an AMG. Thanks everyone.
