3-Series G20/G21 suspension long-term

Any 7th-gen 3 Series long-term owners on here?

I was wondering how the suspension on your G-Series 3er was holding-up after 2+ years and/or 20K+ miles?
I ask as the general interweb and journo consensus was that the passive M-Sport set-up was too stiff and the M-Adaptive was much better even if on the firm side even in Comfort setting. The base SE/Luxury/Sport set-up not often discussed, but seemingly OK but ppl still saying get the Adaptive.
But almost all these opinions were based on new cars and now there are well-used ones on the market how do people find their suspensions - still good?
With previous-gen BMW, not just 3er, the SE & Adaptive/EDC/VDC the dampening often seems to go overly soft and rolly/bouncing whereas the passive M-Sport remains decent even if it has mellowed. Is it the same with the G20/21?

For a used model is the passive M-Sport suspension now the one to aim for dynamics let-alone out-of-warranty repairs?

Hi we have a 2020 70 plate 320d M Sport Tourer with adaptive suspension just turned over 24k miles suspension is amazing , if you get one look out for the pro pack , { black grills , blue big brakes , 19" staggered wheels etc } will be buying another in a year or two .

How are you finding the 4-pot diesel in terms of noise & vibration? I test-drove an X2 20d recently and it was a nice spec but that 2L diesel didn't half make a racket around town and i felt i was drawing too much attention to myself from the noise, i could also mildly feel the vibes through the steering wheel. TBF on the highway the engine noise didn't exist. Also at low town speeds the engine felt sluggish compared to my 220i but don't know if that is a gearbox factor too, the former 8-spd slush-box versus the latter's 7-spd DCT - how's the G21 in that regard?
My 330i is now 3 years old and 60k on passive m sport suspension. I can’t say it feels noticeably different to when new, but when you drive a car every day you don’t always notice things changing over time.

It’s definitely a firm setup but that’s exactly what I wanted and I’ve always been happy with it even on long journeys (just returned from 2500 mile holiday in Europe).

Also strongly recommend the 30i engine. Average 40mpg possible (and petrol cheaper than diesel). V fast. Not sure why it seems to be so rare.

Yeah the 30i is my ideal, however as you said - rare indeed! Most approved-used G21s seem to be 20d or 30e and what 30i there are most come with adaptive suspension, the ones that don't are usually base spec.
F31 are even rarer in 330i guise :-( even more so without high-gloss black trim which i really dislike >:-(
