I get what you mean about the 'Hot Wheels' reference. Once you see it, you can't unsee it! 3 Series coupes looked not too bad with them.I'm one of the few that dislikes the 230 style wheels.
My Coupe had them when I bought it, I tried to like them but they just looked too big to my eyes.
Then someone called my car a 'Hot Wheels' toy car, as the wheels looked huge.
That was it, i couldn't get that image out my head, they had to go.
I changed them for a set of 18" 261 style, then moved to a set of forged 18" 405 style.
