25g is a lot to ask for a cash sale. I’d have to have statements with my bank for any withdrawal or deposit over 10k. They want to know where the funds are going and I would never carry that kind of money around. Asset Forfeiture is a thing.
That being said, you’ve got a ton of great advice here. A bank wire. A check or transaction from same bank to same bank so funds are verified. And PayPal. Though a word of caution with PayPal. If you specify it was a transaction for goods, then they have the right to dispute your transaction and get a refund and the Bronco. Not likely, but can happen. Make sure the transaction is specified as a gift and they have no legal right to get it back.
I used the PayPal gift option when a buyer showed up on Sunday to buy a vehicle for $7k. He drove from NC to PA and everything reeked scam because he didn’t bring cash either, but he agreed to pay it through PayPal as a gift. Turns out he was a great guy, we are FB friends and I still get photos of my Firebird all fixed up.
Above all, you go with the option you feel safe with. Good luck selling!
