To add, I don't feel like the money and time spent on the car are a waste. It's what I enjoy. If not the car, it'd get spent on something else I enjoy. That's what we earn it for right?

OP, how do you know the loud car that you don't like is their life? It's a hobby like it is for the rest of us. How do you know they don't have a family that they spend most of their time with and money on & that car is just their little escape?
