California bases the minimum required emissions standards that a motor
vehicle must pass on the date of manufacture.  A vehicle is not in general
required to pass more stringent standards that those which were in effect
at the time of manufacture.

Keep in mind, however, that the limits for the tests are close to an order
of magnitude higher than the limits imposed on the original manufacturers.
If your vehicle fails an emissions test (even in California), it is either
really out of whack or has been modified.

Leaded was phased out at the end of 1973 in passenger vehicles.  It is
still in use today for different vehicles (100LL avgas, despite being "low
lead", contains more TEL per gallon than 1960's gasoline).
