Things can get really messy if the car is encumbered to two institutions rather than one!
Assuming it's one, you need to gain permission from the seller to contact that institution through a contact person who will also be present on the date of payout and transfer and settlement.
Then you contact that person at that institution to get the final payout figure in writing > scan it > email it to you.
You make out two bank cheques - one equal to the payout figure in the name of the institution - the balance in the name of the seller.
But if you're not going to be present, two EFTs will have to be arranged which is more risky if you don't trust the seller.
Arrange to send the two cheques to the institution in readiness for the date of release/transfer/settlement > then picked up by the transport company of your choice.
Me? I'd fly up there > use two bank cheques > drive the car home!
