Buying A Second Hand Car

[ruby123]

I want to my a car from someone who is leaving thailand but it is on finance right now.They gave around 50% deposit when they bought the car new around 6 months ago and owe around 250,000 baht.

They want me to pay the finance of and give the balance which is around 300,000 baht.The finance company says i have to pay the finance of then come back in 3 days and take the blue book to Transport to change name.This is the quick way of doing it.My only concern here is should i pay the finance of and give them the balance at the same time before i get the blue book in my name?.Thanks.
