The 2015 GL550 turbo is off the rails. Push the sport mode button and some kind of witchcraft happens. It is a fast, comfortable brute that puts many 2023 SUVs to shame. Highway, no problem, B roads, no problem, snow, no problem, heavy rain, no problem. It does it all. Mine was 110K new. I picked mine up used for 40 with 35K on the clock. I use mine like an SUV. We hunt, fish, and put the dogs in the back. It does it all. Do not take your Merc to the dealer. Some folks specialize in Merc and will do your routine maintenance for thousands less. Yes, thousands less. Some of which you can do yourself. I'm on a Mercedes forum. Folks help you with countless features. The Germans know what they are doing.

Owned a newer 2014 S-Class, but we could never get two golf bags in the trunk. It was a beautiful and lots of technology but needed more cargo volume. Bought a 2015 GL450 pre-owned from the local Mercedes dealership. The newer GLS is more expensive and feels less solidly built and tons of electronics that can go wrong. Overall, I am happy with the comfort and utility of this SUV. We took it on a couple road trips in its first year. I have distronic plus radar cruise control and didn't know that it also helps automatically stop to avoid a collision. Some crazy driver stopped in the middle of a highway trying to get into a left lane and I would have rear ended them if I didn't have the radar with the active brake assist. The comand navigation screen is smaller than on the newer ones and the night time backup view is too dark. I've had some glitchy performance with the Comand system, but it's a 7 year old SUV, but it's somewhat to be expected. Overall, great SUV to live with for at least the next 5-10 years before everything goes electric.

Perfect car for us. I've owned 6 other Mercedes over the years and this one is the nicest. Bought it for my wife after she's driven Volvos exclusively for the past 25 years. This was a certified pre-owned and in immaculate condition with low miles. Only downside whatsoever the the placement of the hand holds when getting in the car. Personally I would have placed them more forward for ease of getting in.
