I finally looked into titling and registering a scratch built car in Oregon (not resembling any other car) and came up against a huge roadblock: emissions testing. Unlike a brand new replica which uses as the model year the model year of the car it is a replica of, a brand new scratch built car's model year is the year it actually is completed. Oregon's emissions testing uses that to determine testing requirements so tada - I need the latest OBD system in the car (well - actually no older then 1996). I'm basically looking for people who went through the same thing and have helpful pointers. I figured this board might be a good first step into finding that info. Anyone have any resources or links concerning this?
