A perfectly weighted Carbon fiber knob is as good as an equally weighted resin, or weighted alum...
To each their own. I know he takes pride in his car, but to me I see it as "chintzy". Too much, gone too far. I could not own a car like that, even if given to me. But then again, I don't like women with makeup or in high heels...
