Your sunroof stays open after you pull the key, and you only notice when it rains.
Start/stop turns itself back on every single time you start the car, no matter how many times you disable it.
Your friend's newer 3 Series has ambient light effects and yours just has the same flat white it came with.
Your dealer quoted you a coding session just to enable features that are already built into your car's hardware.
You bought a pre-owned 5 Series and it's missing half the comfort features the newer trim levels have.
