The PIR Auto Swap Meet is one of the largest on the West Coast, and runs every year in conjunction with the Always in April Portland Auto Swap at the Expo Center. Booths for the PIR Auto Swap go all the way around the 2-mile road course, plus fill the paddock and other roads. More than 1,000 booths full of automotive material.
PIR is also prime parking for the two events, and free shuttle buses move between each event.
Admission is only $5 to the PIR Auto Swap.
