I do the same. My car and truck are regi'd in the rogue valley. They still have smog but rules down there are 20 years and newer instead of '75 and newer (or whatever it is up here).
I would have thought you lived right outside the line, i guess your still in portland.
found the info i was looking for:
from:
http://www.oregon.gov/ODOT/DMV/vehicle/emissions.shtmlEmissions testing is required as follows:
In the Portland area, 1975 and newer model years must be tested (view detailed information).
In the Medford (Rogue Valley) area, vehicles 20 model years old and newer must be tested (view detailed information).
In these areas, cars, trucks, vans, motor homes and buses powered by gasoline, alternative fuels (such as propane), and hybrids must be tested.
In these areas, diesel-powered vehicles with a manufacturer's gross weight rating of 8,500 pounds or less must be tested.
Also i have been told that its possible to get around DEQ. i don't know how rumor this is and how real. But something along the lines of claiming a hardship of fixing the problem. The problem being way more expensive than the vehicle itself. I feel like you can get it registered (not trip permit) but i couldn't find more state info about it.
