Do I need to set up an appointment to come in put in a car transfer form

You can just ally in. Gifts get it smog checked first especially if its San out of state vehicle

No you do not have to have appointment

They're currently doing walk ins but I'd recommend going before 3 or 3:30, thats typically when they give out the last walk in numbers

So just come in and fill out the forms

No?

Not that I know of
