I found a Missouri website on statewide standards, at least for now:
"Vehicle Model Year Exemptions: Vehicles 26 years and older are exempted
from the emissions testing requirement. In 2005, the program will test most
odd year vehicles 1981 and newer, as well as vehicles undergoing a title
change model years 1980 and newer."

There is no guarantee this won't change in the future, and doesn't mean that
my car could be sold into a more restrictive state. And some metropolitan
areas may have tighter standards than the state.

[PS shortly afterwards - actually, this _is_ the more restrictive
metropolitan standard. Only a few counties in the Missouri currently have a
testing requirement.]
