It’s amazing how different people have different experiences of what is essentially the same car. You honestly can’t hear ANY wind noise at 70mph? I find I can hear tyre noise from 15mph and wind noise at 40mph. At 70mph wind and tyre noise is so intrusive it requires a significant boost in volume to listen to music. Comparing it to my late 2018 model A6 is like comparing chalk and cheese in terms of noise, comfort and refinement. The A6 is in a completely different league. But then the Germans know how to put cars together properly.
My M3 also has no interior flaws after more than three years, but I can say the same about every car I’ve owned over the last 40 years.
I’m another person who finds the interior of the M3 to be too spartan. Everything seems to be about saving money. A decent binnacle display, a HUD and a few physical buttons for HVAC are a must in my next car. I’m more and more drawn to the EV6 GT. I’ve just heard a reviewer on Fully Charged say it’s (in his opinion) “the most broadly talented electric car on sale right now” and ”we all know when it comes to electric vehicles right now the Koreans are a cut above the rest”. That will have the Tesla fanboys spitting feathers
