how to dispose abandoned personal property of a trustee sales

[James Cheung]

This is my first time buying from a trustee sales.  The house is vacant.  But the home owner left with a lot of personal belongings there, mostly clothes and junks.  But there are two cars sitting in the backyard which are not working.  I understand there is a procedure to follow before I can dispose the personal property, especially if I want to claim the two cars with DMV, selling them to recover my storage or hauling away the trash expenses.  can any trustee sales pro in Los Angeles County advise me the steps I need to take?  Thank
