Hi there, there are no hidden costs!
However, yourself as the seller have to send your car intended for sale to puspakom for inspection. The used car can only be sold with certified puspakom inspection forms. Normally you or an appointed agent would need to send the car to puspakom twice to get the required inspection papers, usually Form B5 and B7 (required by the bank) for private cars. The inspectiion at puspakom incurs small fees, on top of agent’s fee (if you choose to use one).
