Cheap Car Auctions

Im looking to get an ’85-89 camaro iroc-z. I want to get something good and cheap that i can drive and work on. I love those cars. I want to get one from an auction, but everything online is newer late model cars and/or you have to pay to see there inventory. Anybody in socal ever go to an auction that sells kinda older cars? PLEASE let me know. I just want to go there and see what they have. Everything online is a guide to an auction or something like that. aNY HELP WILL BE GERAT.
Thank you!
