It does matter which DMV office you go to. I suggest the office in Lake Oswego. Used to live around the corner from the office. Nice ladies working there, but they don't give a crap about old cars. Just have all your paperwork filled out correctly ahead of time, and be polite, and they will sign off on it. I took my fiberglass t-bucket in to transfer the title from out of state. Car has an assigned VIN number from Arizona. Office ladies walked out, looked at the car, looked at the VIN tag, everything matched and paperwork was filled out right, walked out with a title to a 1920 Ford Model T.
