Oregon emission law states: In the Portland area, 1975 and newer model years must be tested . In the Medford (Rogue Valley) area, vehicles 20 model years old and newer must be tested http://traffic.findlaw.com/drivers-license-vehicle-info/state-emissions-standards-and-testing.html
We have 1 or 2 more years of emission testing for our old 1988 Isuzu Trooper. At 190k miles with a recent reman engine install, it sails through tests cleanly so that's never been a concern. One less aggrivation and $20 saved though. The Atlanta metro area which encompasses about a 13 county area has FINALLY recently emerged from being out of compliance to fed standards for air quality. Sounds like a good bill to pass in Cali.
