There's no 'right' way to pay for a vehicle. The best thing to do is to discuss with the seller how they want to be paid.
Some options could be:
- Online bank transfer - this is probably the safest and easiest way
- Cash - it's worth thinking about arranging the handover at a bank
- Cheque or banker's draft - the seller may want to confirm with their bank that the money has transferred before they hand over the car
Good to know: A seller might also give you the option to pay via cryptocurrency. This method is not regulated like the ones listed above and is, therefore, a risk.
However you pay for your vehicle, the most important thing is that you get a receipt from the seller.
