Help me choose 2021 (E350 vs E450 4 matic)




I test drove both the 2.0 and 3.0 engines. Here is the way I found them: the 2.0l was peppy but not powerful. The 3.0 is powerful, smoother, more refined and I felt belonged in a $65,000 car. Also my gas mileage on the open road, at 65 MPH with my 2019 E450 is 32/33 mpg pretty much the same mileage that the 2.0L engine. I am glad I got the E450 instead of the E300.
Suggest you test drive both yourself and make up your mind. If you truly plan to keep the car for 75,000 miles, 7 years, the difference between the E350 4matic, $56,750 and the E450, $62,000, is $5,250. On resale the E450 should be worth $2,000 more, so the actual difference is $3,250. If you drive 10,000 miles per year, 7 years, the extra cost is less than $600 a year including the extra cost of gasoline in city driving. Mileage on the open road will be pretty much the same.

I purchased a '18 E300 before the v6 was offered. The car is OK around town but fails for highway use. The real issue is that it lacks power going from 45 mph to 65 mph. Going from 55 mph to 75 mph is a real challenge. For me those speed ranges are critical to on-ramp merging, passing and high speed avoidance maneuvers. I have restricted my '18 E300 to city operations exclusively and use an older BMW for highway trips. There are many threads regarding the E300 power issues.





In terms of reliability, BMW is often viewed as the least reliable of the big 3 Germans. And I've never had any major problem (engine, electric, etc.) with Mercs. But the interior quality on Mercs and BMWs right now is simply awful, especially compared to Porsche: creaking, rattles, and flimsy bits galore. A quick search on youtube will give you a rough idea. I love the design of W213 to bits, but the rattles and creaking are annoying to the point of infuriating.
For engines, assuming that you are referring to the US models, I see that E350 still keeps the old 4 pot with 255hp rather than the new mild hybrid one with 299hp available elsewhere. The E450, on the other hand, uses the new inline 6 engine, unlike the pre-facelift version with the tarted up old V6. I think you would want to consider this and decide whether you prefer the much newer engine with better refinement or older engine whose problems are better understood.

they sell it like you are going to drive on clouds, but i feel no difference at all between this & regular suspension
just my 2 cents, don't spend it all at once .

This is actually $2,085 less than my 2019 E450 with the exact same equipment!
Go figure!




Lots of good things to say about posted speed limits in Texas. Posted 80 mph just after Odessa to about twenty miles from El Paso, Texas. Run five over the speed limit works for me.
The seats in my E450 wagon are.......marginal compared to S class or Porsche Panamera 4S.






Do not yell and scream: I use regular not premium gas!
(Tried premium and gas mileage was the same)
Because I typically keep cars 6 years / 25,000 miles air suspension is not something I want.
