Guys,
As the title states, how did you handle a private party car sale? I'm looking to have only serious buyers test drive the car. So how did you do that? I have seen people mention that "please have the money available before the test drive", possibly a cashiers check during meet up? Just write an ad that is uninviting/mean to thwart those joy riders? Not sure how to handle this situation. Can someone let me know their experience please.

Thanks,
