Or even simpler: if $INTERNAL_CLOCK < $PROJECTED_DATE_OF_SALE { fake_emissions; }

Many states in the US force you to test emissions when you register your car.
if(miles_driven < 10,000) { fake emissions; }
You often have to renew this every few years, or when you move to a new state. Even my 16-year-old Chevy Caprice with 200k+ miles had to run the CA gauntlet.

  (unless (car-radio-playing?) ; probably not the owner driving
    (fake-emissions))
I mean that would be a pretty crappy defeat device
