Bad Credit Car Loan

need advice on bad credit car loan?
I’m single and I rent my apt. I have a steady job making 45k year with direct deposit but bad credit. I see advertisements for these bad credit car loan places? Is it possible for me to get an 18k loan without a cosigner in the real world from one of these places or am I wasting my time? Has anyone ever worked for one of these places or been in my position and rec’d a loan & where from, what company?
Auto finance is what I do for a living and your best bet will be to find a large dealer the advertises Special Finance and go talk to the Manager.
Stay away from the buy here pay here places because over 90% of them do not report to the credit bureaus.
In almost 8-years of doing this, I can not remember anyone that could prove their income and had enough of a down payment that I did not get approved someplace.
