first post - seeking owner experiences/opinions
Hey all, first post here but longtime lurker and seeking some experience and thoughts from the ownership cohort. I’m heavily considering a pre-owned C238 coupe for extended commute/business travel purposes and wanted to pose a question of the following two I’m looking at:
1. 2018 E400 with 22k miles for $35k
2. 2021 E450 with 47k miles for $37k
Both are comparably equipped and similar colors. I know there are visual differences due to a mid-cycle refresh and a slight power bump in the ‘21 but otherwise very similar.
So what’s the “better” buy based your experiences: the older car with lower mileage or the newer car with higher mileage? Both are out of warranty with clean carfax.
Anything I should be looking out for/aware/wary of? Does MBUSA offer factory extended warranty coverage?
Appreciate any and all feedback, thanks in advance!

Do you like to work on cars? Does the car have to be reliable? It's a bit of a gamble either way. Not sure i would think mercedes if i had to depend on the car every time without a plan b. Pay to have them both inspected by a mercedes knowledgeable mechanic. The one with higher mileage has been 'proven' but close to more major maintenance by mileage, the oother may develop problems due to disuse, is due for more major maintenance by time and maybe should have had the transmission service done. A good mechanic can find their service history. Someone else will tell you the website you can go to. You would have to buy a non mercedes warranty if you feel the need.

This is a good point, the pre-facelift has the COMAND and the facelift has MBUX. The latter which also have a touch screen for those who need it. That said, for long term reliability, a known reliable engine is important to consider as well.

Without hesitation I would choose the 2021. I own a 2023 e450 4matic and the i6 engine is very smooth and well suited to this car. The hybrid motor adds a nice boost with almost no lag. I had the prior v6 in my c43 (same 366 hp) and I strongly prefer the i6. Also the MBux is superior to Command for reliability and gives you more features on the app. Go with the ‘21 and share a photo!

I have a 2019 with no issues and 35k miles. Love it. I think the 2018 should be cheaper, maybe $31k. They may be more flexible with a seven year old car.
MB are very good mechanically but as you get eight years old stuff like seatbelt won’t retract, plastic cover on hvac controls get small cracks- small cosmetic stuff that’s $1000 to replace.

There are some small differences though even though 2018 and 2019 is not a a facelift, but the steering wheel is different for example. The seat controls is one hold and release and it will automatically adjust to the memorized position but on 2018 and older model years you need to hold it.

I have a 2018 E400 with 35120 miles for sale if if you're in SWFL. About to trade it in next week. Absolutely mint. Even the engine bay.

'18 E400 Cab
I have the 2018 convertible and would absolutely trade it for a '21 if I had the chance, but not one with that many miles. Given the miles and the choice there, I'd go with the 2018, but I recommend you hold off and find a '21 with fewer miles. The upgraded controls are definitely worth it.
