2020 E 450 wagon - Buy or avoid?
My advice is to keep what you have if it's in great shape and you still love driving it. Just for reference, I owned a 2012 E350 up until I totalled it last April. It had 170K miles and looked/ran great. I was planning on keeping it another 5 years minimum, but I hydroplaned and hit a tractor trailer. Total loss, but I walked away unscathed. I ordered a 2025 E450 a week later and took delivery of that last August. It's a great car and rides better than my 2012 did. However, I would gladly take my 2012 back had I not crashed it. It's a 13 year difference and I would say there are only incremental improvements. That's not a dig on the 2025 models, but rather a testament to the 2012 model. It was a great car and I'm sure your 2014 is too. In my opinion, it's not worth the expense to get a newer model unless you have to.




I have a 2013 350 and a 2020 450… so I am speaking from some knowledge here.

Ha ha ha ha ha ha ha ha ha....as the owner of each (I got rid of the 450). Mechanically, I will take my (still owned) 2011 E350 (wagon) over the 2020 E450 wagon day in and day out. Well, unless you have a deep need for the glass dash. Matter of fact, I replaced the 2020 with a 2014 (wagon) that blows the doors off of the E450 in every manner. Never was a fan of the turbo(lag) six....hell, I never even talk about that car.
Do a search. There are many threads on this topic.




HEated steering, armrest and center console are a nice big leap if youve not had them before. Same with HUD and driver's assistance features. Big leap stuff. The 9speed is another big leap. The dynamic drive modes, esp with air body control, are another big leap. Sport+ and manual mode are a hoot compared to what my last w211 offered.
The Panaramic sunroof, ambient lighting, massaging dynamic seats, glide mode, auto parking brake, hold feature, auto/smart multi beam fancy headlights (esp if you pay to have them coded to euro spec) are all very solid improvements if your other car doesn't have them.
I mean, just be picky and find a car that is loaded with all these great features and you will have something where the sum of the total experience is greater. Oh, don't forget the comfort headrests! They're worth it imo and MBrace/Mercedes Me features like remote start and text alerts make the w213 feel like a big leap forward.
I bought a one-way ticket 6 states away to find a wagon that had what I was looking for. No regrets...yet

Remember going from 18" inch wheel to a 19" inch wheel you lose about 1/2 an inch of sidewall and from 19" to 20" another 1/2 inch. The decrease in sidewall is the primary cause of the rough ride.
The one exception is the air suspension: with air suspension the number of complaints decreases dramatically. However, when you read about the air suspension it seems universal that after the warranty period, problems arise and the repairs are very, very expensive. If you plan to keep your car beyond the warranty period and have air suspension be prepared for substantial repair bills.
Hope this helps.

You may be a "unicorn" and atypical and hence not representative of most drivers.
I buy new tires based on tire age not tire wear.




When we comment on ride quality, I think most of us are talking about on the road, not stop and go traffic or local traffic:
Most of us change our tires based on wear not age: age does not become a factor until minimum of 7 to 8 years.
Again, you may be a unique situation, changing tires before they wear out, atypical and not representative:
Here, tires start to weather check around 4 years in the semi-tropical Florida sun. (Unprotected skin burns after about 20 minutes of direct sun.)
Often my tires also run over 130° F after a few minutes of driving which increases tire wear.
That being said, tire tread remaining when tires are replaced is a personal decision. I consider tires with only 5 mm of tread remaining as needing replacement.
That's about 10k miles or 4 years

- I cannot tell the difference in stop and go traffic as you can
- Temperature of tires does effect wear: that is why there are wear bars on every tire
- The tire bars are set at 2/32 of inch. Most people replace at that height
- New tires are either 8/32 or 9/32
- You replace tires at 5/32 which means you have between 40% and 50% of tire tread life still left when you replace your tires
- Most people garage their Mercedes so sunlight is not a problem
I also remember you posting that you change your oil every year, so that would be every 2/3,000 miles and brake fluid every two years, so that would be every 5/6,000 miles. I suspect you will also change your spark plugs at five years, between 10/15,000 miles and your transmission at the same time.
No disparagement meant or intended, but you are not typical or representative
