Mar. 12th - 29th All Oldsmobile Car Show at Pavilions, Scottsdale
9 am - 1 pm
Surprised that nobody has mentioned this show. It should be pretty big. I'm just happy to have this coincide with my time down in AZ. I'll be there.

 

There were about 70 cars there. Some were awesome vehicles. It was a morning show 8-12. The big Pavillions show is mid afternoon till evening every Saturday. Usually 400+ cars, some very high dollar.
