Ok, I just took my car for the first drive after following this and Sport Plus is definitely noticeable over Sport. The only performance mod I have on my 2019 330i is a Dinan cold air intake, but in sport plus it’s even louder. I feel like you can hear the turbo a little more and the car is overall a little more responsive and definitely louder with more noticeable pops from the exhaust. I think it’s worth it, just my opinion.
Never mind the build quality. Look at the depreciation of these EQS models. People are buying these new for 140k and selling them for 80k only 1-2 years later.
Mercedes making their entry level cars cheaper and cheaper every year just to see how much people will sacrifice for a $50k “status symbol”. They still do make some great cars but be prepared to spend six figures on the top end stuff. G wagon, S class, AMGs, etc.
