How fast are bank transfers over there? In the US we have "same day" for small amounts, and a multiple day long clearing for bank to bank personal transfers for larger amounts, ie what you'd pay for a car. Then you'd need a bunch of their banking info.

I don't know about your experience, but I'd like to limit the amount of PII I give to the type of folks I buy used vehicles from. With cash, you both go on your way with the title. Its not to say they were criminals, but I also don't have much reason to trust them beyond the transaction.

For example, I was helping a friend buy a motorcycle. The seller arrived on the bike, we checked it out, paid, etc. He had a shirt on that said something like "stop domestic abuse". Then when his wife/gf/partner showed up to pick him up, he immediately started throwing verbal abuse at her. The guy was unstable but it wasn't immediately obvious. We already had the bike, the title, and we were on our way.
