Cal Henry at IM, Vancouver for his guidance. There are several IMs in WA/ Seattle, none of which require testing due to how they have been registered/titled in WA. They will require a Washington State patrol inspection as part of the title process.
also, the WA state patrol may be able to answer some questions regarding how to title/ register/ apply for emissions exception for you specialty collector vehicle.
WA laws changed in late 2014 and throught 2015... Now all 2009 or newer cars must be certified and meet California emission requirements...
this is the new form to apply for your emission exception for collector cars if registered title YOM is after 2009. Unfortunately most folks I have talked to at DOL offices can't really answer basic Qs... Call their hotline and see if the can point you to someone in their office/WA state patrol or DMV that can answer your Qs.

I'm not familiar with the new process, but followed the changes last year as they came into affect....
