Ignorance is likely the biggest part of the reason. I do a lot of analysis when I’m researching a vehicle. She operates differently, and simply drives a bunch and looks within a specific price range she s comfortable with. I try to do as much helpful research as I can, but I’m often involved after she has made up her mind. She has a funny sense of vehicle size. She considers a lot of cars too big. She liked the feel of this GLC300, I don’t know much about the models you mention. In the end, she is happy and it is under warranty for the next 3 years. I’m trying to learn what I can and keep the maintenance up sufficiently.
I appreciate the additional information; it may come in handy if she starts having serious engine issues.
If I had my vote we would have purchased the CPO BMW X6 she test drove; that car was a runner and quite comfortable, but it was “too big” for her.

For me, it aimed my right leg at the brake pedal so I sometimes hit it when I needed the gas pedal.
We should have gotten the 14 way seats.
The Q5 and Q7 seats were firmer than either of us liked. Not the Macan, or our Cayenne for that matter.

The 53 is too big for her, and for me if truth be known, but we need cargo space and the ability to tow heavy RV's.
The AMG ARC in the 53 was the solution to "feeling much smaller" and restoring nimbleness for my car.

The 18 way seats are too narrow at the front, and kind of "bit" our thighs, forcing our knees together.

We're not afraid of the GLC four cylinder. Don't see any reason to. The 43 seemed slow and noisy, so not an option.

All this talk of “head issues” reminds me of the early 3.6 issues in the Jeep Wrangler. Also, talk on the Ford forum about the 6.2 issues in the super duty trucks. One thing about forums is problems are what a large percentage of users come to ask about. It is rare someone joins to say “Hey, my [insert car model here] is running fantastic!” This leads people to infer there is a huge problem. I wager the percentage is smaller than people say because of the percentage of owners that join a forum? I’ll bet is is < 3% if even that. I’m not saying there is no problem, but I am saying the odds are not as high as the forum posts indicate.
Beware of the “forum effect” for issues. If it affects you that much that you trade, perhaps you should stay off forums.
Reading these posts it is like the road is littered with MB 4-bangers with 50k miles and a blown motor.
My wife just picked up a CPO 2023 coupe, so still an x253 with no hybrid crap. It has 25k miles, and she drives 20k a year, so in 18 months we’ll see what happens. She traded in here 2019 Macan S w/85k miles for this. This is her first MB after many years of BMW and a few Porsche models.
It sounds like the OP made the best move for their position given the fear of catastrophic failure despite no current signs. You should not live in fear and if it takes changing vehicles than good move if you can afford the $$ loss.

The posts of people with the m264 head issue on sites like Reddit make it seem very common when 10 of 15 posts in a thread said they had the issue. How many more had the issue under warranty that didn't care or aren't posting? Large portion of the sub or forum users have the issue.
3% you'd still be talking over 30,000 impacted GLCs plus the other models with the same engine. MB has over half a dozen part numbers for the m264 head so they appear to have kept revising it during the short production run. The price for the head kit now being ~$800 tells me they are making a lot of them to drop the price down.
