2021 - Now at 89,000 miles
Hey guys
I bought my GLS63 with 2500 miles on it and its been great zero issues. I have had it renntech tuned since I got it and done my normal services, I have CPO warranty until mid January and debating extending and keeping or selling and getting something newer. I havent seen anybody with one of these vehicles with this many miles on it yet, what type of maintenance should I be prepared for coming up or proactively? Love the vehicle but debating going to a larger SUV if major stuff coming up.

What do you think of the suspension? My 2021 feels horrible over pavement gaps and sharp impacts. There is a low frequency resonance that doesn't seem right. The dealer replaced the entire driver's side shock assembly which helped somewhat but still seems abnormal. Just not solid like you expect from MB.

The big, expensive services are coming. Plan for the transmission service and spark plugs soon, if not done already. Check if your CPO warranty covers the air suspension struts - those are a known wear item and very costly. At your mileage, they're a prime candidate to fail. Factor that in before you decide to keep it. If you're worried, selling while the warranty is still active is a smart move.
