Is this the right group to be in




Jokes aside - spend some time reading the threads. The X167 platform hasn't been around for too long, but there are a few of us original owners around with higher miles now that are entering the 100k club. I'm one of them.
Mine has been fine. Some interior quality issues here and there, but mine was a Covid era 2020 build and MB has fixed them for the most part. Things like squeaking window operation on the driver's door, MB tex spitting on the front seats, a repeatedly broken rear door seat control and popped out heated seat button. Superficial stuff.
Mechanically speaking - ours has been 100% flawless. We're still on the original brake pads with 30% left at 95k miles. The rotors are wearing out before the original pads! We're also still on the original 12v starter battery as well. The suspension bushings and mounts in this thing are stout. You shouldn't see any problems from them. I just had my oil analyzed for the first time, the internals are 100% perfect. 6 years, and it's asked nothing from me. But, I also change my oil every 5k-6k and not 10k. I change my trans fluid every 40k-50k and not 60k per the manual. I maintain mine. I don't abuse it, it's a suburban country club family glider.
If your first Benz - my #1 top recommendation - find the local indi mechanic and use them, do not mess with the dealer. They are insanely expensive, and this car is extremely easy to service. Our dealerships charge around $700 for an oil change service. The key to owning a MB is all in the indi mechanic 99.9% of the time.
Tires: If you're looking at one of the GLS's with a "staggered" setup, whereby the rear tires are wider than the front - then expect to be replacing the rear tires about every 25k or so. They wear fast. I would give strong reconsideration if you're looking at the AMG package. Go to Tirerack.com and check out replacement tires before you decide which GLS to get. Those with the larger 23 inch tires are not thrilled by the slim pickings for tires, mostly summer only tires. The standard 21's staggered, Michelin has produced a set of Primacy's for many years that most consider to be the best for the car. It's what we've had on ours since 25k miles and we switched from the OE Pirelli's. 0% complaints, the most affordable option as well, and easy to get.
Windshield Wipers - MB has some crazy lock on the universe whereby you're stuck with just their wipers. They can be quite annoying. Hard rubber, chatters, etc. That's just Mercedes for you though, not specific to one model.
Transmission - I don't think any of us have seen one fail completely, but many of us (across multiple models) do complain about how lumpy it can be when coming to a slow and gentle stop. There is a software fix for it apparently (I've not done it), but just know when you go for a test drive in one and come to slow stop, if you feel kicks as it's shifting down from 4th towards 1st, it's normal. Doesn't happen all the time, but it does happen. Driving in "Eco" mode helps quite a bit, and the 450 engine is right at home in Eco mode. It's not struggling or underpowered by any means.
Engine - I'd have to say this 3.0t I-6 has to be one of the greatest 6 cylinder engines I've ever experienced (52 years old). It is an absolute peach. Smooth as glass, quiet, and very capable of making these big German cows get up and GO!! But when matched to the 48v hybrid motor, you absolutely do not have to stress the engine whatsoever to drive it in traffic. Honestly, ours rarely ever sees much past 3k rpm in general. It just glides along effortlessly. But when you ask it to go, it will absolutely go, much faster than you would think for such a big car. And it sounds great when it does! Easily one of the best I've ever experienced. We've had 0% problems from ours.
Maintenance: Just my own opinion here, but I think a reason why we've had 0% problems is because I did a tip/tail service at 50k for every drop of fluid, all filters, and the plugs. I like to reset my cars at 50k, and that has served me very well over the years.
The only issue I've had was recently. I changed all of the driveline fluids (two differentials and the transfer case) and encountered a humming problem from the transfer case. Learning curve moment, solution found, no issues thereafter. It has a unique limited slip setup that requires a certain procedure to flush and clean.

For those drives, you definitely want the GLS 450. We routinely see 28 MPG in ours even still for road trips. It’s actually far better on gas than the 2013 Toyota Highlander 3.5 V6 that it replaced.
Total personal preference, but we love the beige interior in ours. Makes it light and airy, easy to clean and maintain. Cabin is perhaps one of the nicest places to spend time in. Do recommend te second row as a bench and not captain chairs. Hides the cargo area better, lets the cargo tontoe cover work better, and you can fold down the middle section to act as a bigger arm rest if you want. Tons of legroom in the second row too! TONS!! Very comfortable.
XM Radio subscription, set the cruise control, and enjoy. That’s exactly what it meant for, and in my opinion is unmatched in the market.
these rims are the non-AMG staggered setup. We have them, and they’ve been excellent. Have taken some serious pothole hits, no issues. Michelin, Continental, Pirelli all make all season tires for them. Rears last about 25k to 30k miles at best. Fronts last like normal.
When I bought ours, I specifically avoided all things AMG after my 2014 E350 with the AMG sport package. Nothing AMG related lasted on that car. Not even the little trunk lip spoiler. Even it failed. Rims bent all the time, brakes warped within 20k miles twice, etc. Put regular MB brakes on it, knock off rims, 3m tape on the deck lid, and all was fine. I’m not a fan of AMG.

For the insurance, it depends. I have a spotless driving record, zero tickets and zero accidents, with 3-4 cars on my insurance over the past 2 years since I got the GLS, and maxed out credit score 800-850. My monthly insurance payment detail are below.
GLS Insurance cost: $79 per month ($475 6-months)
Company: Geico
Coverage: I selected the max for everything possible (500/500/100 property liability, and 500/500 for uninsured motorist). Could have probably dropped the insurance with lower selections but in a world like this I'd rather not.
Deductible: 1000 USD
Rental coverage: Yes
Others? I have other family drivers on the policy with clean record too.
Property/house coverage: I don't have any of my properties with Geico, and was told could have been even lower if I add any but I have a separate StateFarm policy for that part.
Other cars on the policy: Over time, I had 3 other vehicles (and now 2 other cars) on the same policy, and the insurance rate above has been the same, with similar coverage. The rate above is for the GLS only.
I was with State-farm about 1.5 years ago. Insurance premium coverage was same, and cost wasn't much higher.
