Not sure what to think on this one. I'm no fan of CA's often heavy-handed and overly politically-correct bureaucracy, but we all gotta breathe. Are "collector cars" causing a smog problem? No. But just today I was sitting at a stoplight behind a rusty POS mid '70's Ford that was running so rich it literally made my eyes water. Should that be exempt from smog testing?
