It seems to vary from state to state. I'd be curious to hear what form(s) your state requires.
One unofficial VA DMV site simply says "If you do your customers the courtesy of handling their title and registration paperwork when you sell them a car, you will need Form VSA 17A (Application for Certificate of Title and Registration)."
Here in Idaho, the DMV has a "special" form #3204 for dealers to use. It's literally 7 blanks to fill in - title type, owner's name, make, year, VIN, control number and fees.
If you are financing, then the bank will have their own requirements.
Maybe y'all can define your terms - white sheets, pink slips, the new red flag regs, etc.
Doesn't look like rocket science looking in from the outside, so shed some more light for us please.
