If the owner calls within a day or two and wants to dispose of the car I try to get the hook up fee (usually 150-200) and the title, by the close of business the following day. You have to put a short time limit or it just drags on and on. If the owner has no title NY DMV has a form we can fill out for a car over 8 years old and worth less than $1250, only good for disposal at a registered salvage yard. We fill that out with a copy of license and registration and keep it with our own release and paid tow bill.
