If you're both local, going to your bank and exchanging title for cash or cashier's check at the time would work. You could also use something similar to Chase QuickPay or Citi Popmoney (you must have seen the ads on TV - if you watch TV) where you "email" or "text" money to someone although there is a limit to the max amount.
Forget the text/email gimmicks, those are for small amounts of money. Save that for giving money to a friend you owe
I sold two cars and got paid by going to the buyer's bank with him. I got the bank's check payable to me, at the counter, so I knew it was good. I handed over the title and the new owner drove away. Easy peasy for both of us.
I have a lot of experience in this area so a few questions will help you out:
a) If you are both local enough to drive / meet at a bank, go with this method since it's safest inside a bank since highly unlikely he will rob you with cameras everywhere. Assuming he wants to be paid cash this is the only option. I would never count cash elsewhere.
b) Ask him where he banks - if you both share the same bank, an inter bank transfer is immediate and absolute safest.
c) Ask the buyer if he is ok with a cashier's check from you. For me, I won't accept it unless he will accompany me to MY BANK to deposit it.
Up until the point I deposit it with a time stamp, he can call his bank to cancel it which few people know or understand.
d) If you plan to wire him money, it takes up to 1-2 full days to really clear. Unlike movies where you see drug dealers wire money using some fancy computer, in real life normal situations banks need 1-2 days to clear. In other words if you plan to withdraw the money right away you need to wait. It's not instantaneous.
e) I don't know the amount you plan to pay but if it's under $10k usually I prefer cash but over $10k I prefer to go into a bank. Ask the seller what he prefers since you need to make this comfortable for him, not convenient for you.
When buying PP cars, a little bit of trust needs to be given on both sides, if I have a gut feeling something is wrong, I walk, better to not get a sale then to deal with headaches after the fact! :redface:
