They definitely have a notice of sale available to them if they are a well-run CA. For a certain company we work with, we are able to request the notice of sale, notice of deficiency, notice of repossession, and all documents relating to the repossession. For the other one, we receive all documents related to both the applying process & the repossession process.
I think what people really don't understand is how little your car really is worth, and it's worth even less in an auction. Your car is NEVER going to match up to the amount owed on the loan. Not to mention all the fees they will add - there are a million of them.
About half our debtors are in debt because they did not purchase some sort of GAP insurance. They get in crashes and their cars are hardly ever worth what the insurance company will pay and WHAM thousands of dollars you owe on a crashed car.
Often, a CA will settle with you for the principle of the debt, and lop off all the interest and fees. Don't let them sue you - it's pretty easy for us to win in court as long as we have good documents.
sorry
