Those people are absolutely toxic and have nothing better to do than compare their own success/achievement to others.
I'm currently leasing two BMWs: F30 320i and G20 M340i shared between me and my wife. When my F30 320i lease is over, I'm planning on getting a Honda Civic or a Kia Soul EV for my daily 40-mile commute. Your 330i is so much better than that!
As long as you're satisfied with your car, people can shove their own opinions up themselves. At the very least, keep it to themselves for their own sense of entitlement.
